EMI LEADED FILTERS
TABLE OF CONTENTS
Based on more than 30 years of ceramic and ferrite
technology experience, Murata Electronics’ full range of
leaded EMI filters have been designed to meet today’s
electronic industry requirements.
Murata’s leaded devices consist of ferrite bead inductors,
feed-thru capacitors, 3 terminal capacitors, varistor/capacitors
common mode chokes and block filters.

FERRITE BEAD INDUCTORS
BL01, BL02 & BL03 Series
248 CG01-I
Ferrite beads are used for noise suppression in car radios,
digital control equipment and for the prevention of spurious
oscillation in radio frequency amplifiers. These ferrite bead
inductors are devices which can effectively be used on
printed circuit boards where high component density is
essential. Taped and reeled types are also available for
automatic insertion. Radial leaded units can be classified
into two types — one using a single ferrite bead and the
other using two ferrite beads.
FEATURES
■ High component density potential
■Double bead BL02RN2 types offered for more effective
noise suppression
■Taped and reeled radial and axial types for automatic
insertion can be provided as well as ammo packaging.
■Axial lead version BL01RN1-A62 available
APPLICATIONS
Micro computer, switching regulators, digital control
equipment, car radios, car stereos, etc.

Disc-type EMIFIL®DS310, DST310 and DSS310 are T-type
EMI suppression filters. The disc-type EMIFIL increases
the self-resonant frequency of the capacitor by attaching
two lead wires to one of the electrodes of the capacitor and
increases the insertion loss by adding inductance to the
lead in the DST and DSS types only. Frequencies to be
suppressed can be selected by choosing the capacitance.
They are also recommended for use as by-pass capacitors.
*Note: DS310 Series Footprint for Bulk and Tape & Reel are different. Consult your local Murata Electronics Sales Office. All DS310H units are rated at 7A max. and 250VDC.
Current rating is 7Amps for bulk packaged units, 6 Amps for tape and reel.
Available as standard through authorized Murata Electronics Distributors.

VARISTOR-CAPACITOR
The DSS710 uses a capacitor element which provides the varistor
function. This varistor-capacitor not only works
as a bypass
capacitor but also lets high-voltage surges flow to ground.
The varistor-capacitor used in the DSS710 has a 3-lead structure,
so that its high frequency functions are substantially better than
those of conventional capacitors. Furthermore, it is combined with
ferrite bead to form a T-shaped filter circuit that most effectively
suppresses EMI.
The DSS710 efficiently removes fast-rising transients and
high-frequency EMI above 50 or 60 MHz which conventional
capacitors and varistor-capacitors are incapable of removing.
Varistor-capacitors are used even where conventional EMI-filters
fail. They are self-healing and effective in circuits having
500-600V impulses.

EMI SUPPRESSION FILTERS
VARISTOR-CAPACITORS DSS710 Series
The reason the 3-terminal structure provides excellent
high frequency characteristics.
Bypass capacitors should logically be able to remove
more noise as frequency increases. In actual fact, the
electrodes and lead wires of the capacitor have series
inductance as shown in Fig. 3, and this causes an LC
resonance when the frequency is between 1MHz and
50MHz. As a result, when the frequency is higher than
the self-resonance frequency, the noise suppression
capability of the bypass capacitor is drastically reduced
because the capacitor functions as inductor. To solve
this problem, the DSS series has one side of the capacitor
electrodes connected to two lead wires. This eliminates
the series inductance to the capacitor. Furthermore,
a ferrite bead is attached to each lead wire to form a
T- shaped filter, thus providing efficient noise suppression.

USING THE BNX SERIES EFFECTIVELY
The block type filter effectively prevents unwanted reflections
and external noise from entering the equipment circuitry and
power lines by grounding all the high frequency components
which make up the noise.
To maximize performance, proper grounding is required. To
insure proper grounding, observe the following points:
■When designing the PC board, use all the available
grounding terminals and arrange the circuit to maximize
the area of the ground pattern.
■Minimize the distance between the PC board ground and
the filter ’s grounding plate.
■Insert the filter into the PC board up to the terminal roots.
■Do not externally connect PSG to CG.

Since the input and output terminals of these feed-thru
capacitors are isolated and the inductance on the grounded
side is very small, they can be used effectively to very high
frequencies.
These devices are suitable for suppression of radiation from
TV tuners, car radios, car stereos and transmission devices
and provide enhanced protection from external noise sources.
These subminiature feed-thrus, which may be incorporated in
2.54mm pitch connectors, are ideal for miniature electronic
equipment.
FEATURES
■ The use of barrier layer capacitors has resulted in smaller
size and larger capacity than possible with conventional
capacitors.
■The nickel alloy electrode is resistant to soldering heat and
is free from migration in high humidity environments.
■Compact electronic devices can be achieved by
incorporating this capacitor with a 2.54mm pitch
packaging density – such as installation in connectors.
■Simple construction allows mass production assembly
techniques.
