For Maximum Design Flexibility
Advantages
AMPHENOL OFFERS FILTER CONNECTORS,
WHICH CAN INCLUDE:
• EMP protection using diodes
• EMP protection utilizing metal oxide varistors (MOV’s)
• Filtered plug connectors
• Glass fused hermetic seal
• ESD protection
• Combinations of ltering devices within one

Options
ADVANTAGES OF FILTER CONNECTORS:
• Reduction in overall weight and space with the
elimina tion of external lter circuits
• Reduction of solder junctions
• Increase in reliability due to fewer connections
• Fragile lter elements protected by connector shell from
handling and environmental damage
• Pre-testing from factory and ready for installation
Amphenol provides a wide range of ltering solutions. You
can select your options for your particular interference
threats - VHF, UHF, MF1, HF or other lter ranges, then
couple with a connector package of your choice. Or give
Amphe nol your custom shell design requirements for as-
sistance in designing your unique lter solution.
EMI Filter connectors are intended for use in temperatures
from –55°C to +125°C. Attenuation will change with feed-
through current and temperature.
To assure reliability, connectors may be subjected to an
attenuation performance test verifying proper assembly
and grounding of the lters. Attenuation data on lter per-
formance is stated in reference to a 50 ohm impedance
system in order to allow lter performance to be more
eas ily translated into real world impedances. Those inter-
ested in determining the expected lter perfor mance in an
impedance system other than 50 ohms may refer to page
285 of this catalog or may contact Amphenol Aerospace
for further assistance.
IT IS SUGGESTED THAT THE USER(S) ANALYZE
THEIR SYSTEM REQUIRE MENTS FOR EMI
PROTECTION IN THE FOLLOWING AREAS:
• Working voltage (DC or AC and Frequency)
• Peak voltage
• Desired attenuation at a given frequency level
• Any special capacitance limitations

The Amphenol® EMI lter connector utilizes planar capacitor
technology to provide the user with the most reliable and
cost effective performance across the frequency range. (See
MOV and Diode pages 71-73).
Several array congurations are available, see page 274 for
illustrations. An encapsulant of oven-cured epoxy in the rear
provides:
• Mechanical and thermal insulation of the ceramic
elements – mechanical loading can be accomplished
without capaci tor damage.
• Pins can be bent 90° and straightened with no damage
to the lter.
• Hermeticity (4.6x10-3 cc/sec) – prevents water from
enter ing through the rear of the connector in high
humidity envi ronments.
• Amphenol recommends using metal protection caps
during cleaning operations.

Amphenol® EMI Connectors are produced with several types of lters.
They are all low band pass lters with the following congurations:
Filter Selection Data
C
“C” lters involve a single capacitor. This simple,
cost efcient design excels at low frequency
performance which often exceeds the
performance of multiple-component con-
gurations.
L-C
“L-C” lters excel when the source imped-
ance is less than the load impedance, often
outperforming “PI” lters at frequencies
lower than 10MHz
21
L1
C-L
“C-L” lters are the inverse of “L-C” lters,
performing best when the source imped-
ance is greater than the load impedance
21
L1
T
“T” lters combine the advantages of both the “L-C” and
“C-L” lter types in one package, with superior high frequency
performance.
2
C1
PI
Typical of MF1, VHF and UHF designations, “PI” lters are the
workhorse of the lter industry. Combining performance with
cost efciency, this three-component lter has a steep inser-
tion loss curve, and excels at frequencies above 10MHz. “PI”
lters work well with a combination of different source and
load impedances
21
C1 C2
L1
CASCADED PI
Typical of the HF1 designation, “Cascaded PI” lters contain
three shunt capacitors and two series inductors, resulting in
a very steep insertion loss curve, outperforming all other lter
congurations at frequencies above 10MHz.
UNBALANCED PI
“Unbalanced PI” lters have all the advantages of “PI” lters,
with superior performance when the source impedance is less
than the load impedance.

Impedance Matching Formula
(Your System to a 50 Ohm System)
The following formula and example are offered in order to
deter mine the expected lter performance in an impedance
system other than 50 ohms.
With the attenuation expressed in 50 ohms and the transfer
impedance curve shown in Figure 1 below, a designer can
relate the expressed attenuation to the input and output
imped ance of their circuit.
Example:
(1) Noise is 40dB above specication level at 100 MHz
(2) Output and input impedance are 10 and 100 ohms
respectively
(3) Amphenol® VHF 7000 pf lter has a 65 dB minimum
attenuation at 100 MHz and +25°C
Formula (Taken from Figure 1):
1.4 x 10-2 ohm = transfer impedance
for 65 dB in a 50 ohm system
Atten (dB) = 20 log10 1 +
ZS = source impedance (output)
ZL = load impedance (input)
Z12 = transfer impedance
Atten = lter performance in a system other than 50 ohms
Atten (dB) = 20 log10 1 +
Attenuation = 56.3dB
In this case, the 7000 pf VHF lter will give 56.3 dB which is
16.3dB below the desired reduction in noise (40dB) as stated
in the above problem.

ACCEPTANCE TESTING
All lter connectors undergo extensive acceptance testing to
assure product quality. An outline of standard accep tance
testing performed is as follows:
MECHANICAL INSPECTION
• Dimensional inspection of shells, keys, keyways and
mount ing surfaces by either in-process inspection of
components or inspection of nal assemblies.
• Visual inspection of contacts, inserts and seals, gaskets and
surface nish of shells and hardware.
ELECTRICAL TESTS
• Insulation resistance of lter contacts is checked 100% at the
working voltage and to the test limit listed for each l ter in
the lter selection data table.
• Dielectric withstanding voltage is tested on 100% of lter
contacts at the voltage listed in the lter selection data table.
• Capacitance is tested 100% at 1KHz.
SPECIAL TESTS/PROCESSES
In addition to the standard acceptance testing and processes,
the following additional production testing and processing can
be provided upon request:
• Automated attenuation testing (through 100 MHz)
• Attenuation testing available through 1G upon special
request. Contact Amphenol Aerospace in Sidney for
additional details.
• Leakage inspection

QUALIFICATIONS
Amphenol® lter connectors have been qualied and are on
periodic requalication to specication BSF-1 (available
from your Amphenol representative). This is patterned after
MIL-DTL-38999, modied to include mechanical and
environmental testing and electrical parameters important to
lter connector performance.
These acceptance tests, along with exhaustive in-process
inspection and testing, give Amphenol® lter connectors
their reputation for reliability.
ATTENUATION TEST CIRCUIT
There are multiple test stations
located on the Amphenol production
floor that support all in-process,
final electric and qualification
testing as necessary.

A plug with a given rotation letter will mate with a
receptacle with the same rotation letter. The AB angle for a
given connec tor is the same whether it contains pins or
sockets. Inserts are not rotated in conjunction with the
master key/keyway.
AB angles shown are viewed from the front face of the
connec tor. A receptacle is shown at right. The angles for the
plug are exactly the same, except the direction of rotation is
opposite of that shown for the receptacle.

FLJT – MIL-DTL-38999, Series I
Features, Alternate Rotations
A plug with a given rotation letter will mate with a
receptacle with the same rotation letter. The AB angle for
a given connec tor is the same whether it contains pins or
sockets. Inserts are not rotated in conjunction with the
master key/keyway.
AB angles shown are viewed from the front face of the
connec tor. A receptacle is shown at right. The angles for
the plug are exactly the same, except the direction of
rotation is opposite of that shown for the receptacle.

A plug with a given rotation letter will mate with a receptacle
with the same rotation letter. The AB angle for a given
connector is the same whether it contains pins or sockets.
Inserts are not rotated in conjunc tion with the master key/
keyway.
AB angles shown are viewed from the front face of the
connector. A receptacle is shown at right. The angles for the
plug are exactly the same, except the direction of rotation is
opposite of that shown for the receptacle.

The Amphenol® Energy Shunting Assembly (ESA) is a simple, compact
unit which provides lightning and electromagnetic pulse (EMP)
protection of systems in which many signal lines enter sensitive
electronic equipment. The efcient packaging of the ESA circumvents
the concept of one protective device per line. It provides a surge arrestor
which has the advantage of space sav ing and simplied assembly when
compared to current protective devices which range from diodes to
large spark gaps.
The current ESA design consists of two 53-pin contact,
Mil-Stan dard, hermetic connectors assembled back to back, and
encom passing a ground plate. A sealed chamber is formed within
this thru-bulkhead unit, housing 53 in-line spark gaps. Introducing a
controlled atmosphere enhances fast rise breakdown.
The ESA can be integrated with an EMI lter connector which can
improve its performance. These two assemblies provide a method to
help protect against lightning, EMP, EMI and TEM PEST effects.

Amphenol has developed cylindrical and rectangular
connectors which protect sensitive components from
Electrostatic Discharge (ESD) without diodes, varistors, gas tubes,
or “experimental” semi-conductive materials.
These connectors utilize the Faraday Cage principle to shunt
electro static discharge events to the conductive enclosure on
which the con nector is mounted, thus never allowing the high
voltage, high current discharge event to reside on any contacts.
The ESD protected connectors have the same physical envelope
as their standard counterparts, and do not require special
mounting or ter minating techniques. All of the contacts remain fully
functional, and electrical characteristics such as capacitance are
not effected.
PRODUCT FEATURES:
• Connector envelope identical to unprotected design for
most applications
• Exceeds protection requirements of IEC 801-2 and
MIL-STD-1686:
• Ensures that all components within a conductive enclosure
will be sub jected to a maximum of 10V during electrostatic
discharges between –26 KV and +26 KV
• Voltage observed on contacts during ESD events –
<10V (at 1 megohm)
• Current observed on contacts during ESD events –
<100 milliamperes (at 2 ohms)
• Response time – instantaneous
(voltage and current are maximum values)
• Maximum ESD voltage – tested to ±26KV
• No capacitive loading
• Eliminates the need for discrete components (such as
diodes) and max imizes printed circuit board real estate for
equipment housed in con ductive enclosures which require
ESD protection as free-standing units
• Operating voltage of connectors not affected for most
designs
• Pulse life – innite
WHAT IS ELECTROSTATIC DISCHARGE (ESD)?
Electrostatic Discharge (ESD) is the rapid transfer of a static electric
charge from one body to another. A static electric charge consists
of either a surplus or depletion of electrons on a body, which gives
that body a potential or voltage relative to ground (or another
body). The discharge is extremely fast (less than 1 nanosecond
risetime) and the current ow may exceed 100 amps!
Static electricity is normally the result of two materials transferring
charges when rubbed or separated, such as shoes scufng across
a dry carpet, or sheets of untreated plastic being separated. This
phe nomena is commonly referred to as the triboelectric effect.
The voltage developed due to the triboelectric effect depends on
the materials involved, the quantity and type of contact, and
relative humid ity. In a dry environment a person can accumulate a
charge of up to 25 KV! In a moist environment a person’s
potential is reduced due to the effect of moisture on the insulating
properties of materials.
WHAT IS A FARADAY CAGE?
A Faraday Cage is a conductive enclosure. It may be solid in form
such as a sheet–metal enclosure, or it may be full of apertures,
such as a wire cloth box. When a charge is placed on a Faraday
Cage, the electrons which make up the charge, having like polarity,
try to position themselves as far as possible from each
other. This places the electrons on the outer surface of
the enclo sure, leaving the inner surface uncharged. The
charge on the outer surface does not induce a charge on
any neutral object inside of the Faraday Cage, and
therefore does not try to transfer itself onto the internal
object. Neutral objects (such as IC’s) inside of a faraday
cage are thereby
protected from ESD activity external to the Fara day
Cage.
The voltage and current observed on neutral objects
within a Faraday Cage during ESD events are due to the
secondary effects of ESD. These include Electromag-
netic Interference (EMI), magnetic and electrical eld
coupling. The Faraday Cage of the Amphenol ESD
Protected Con nectors has been designed to minimize
these effects.
THE AMPHENOL® ESD PROTECTED
CONNECTORS
The Amphenol ESD Protected Connectors have a
Fara day Cage at the mating interface. The Faraday Cage
has been specically designed to intercept electrostatic
dis charges from the contacts in the unmated state, while
maintaining each contact’s isolation when the connector
is mated. When the ESD Protected Connectors have
been mounted to a conductive enclosure, a Faraday
Cage is created which will protect components located
within the enclosure from electrostatic discharges. This
elimi nates the need for discrete components such as
diodes and gas discharge tubes, and saves printed
circuit board real estate. Amphenol ESD Protected
Connectors have also been applied to Line Replaceable
Modules (LRM).*
