Philips Components Product specification
Varistors 2322 592 to 2322 595
FEATURES
•Zinc oxide disc, epoxy coated
•Straight leads
•Straight leads with flange
(2322 592 and 593 series only)
•Kinked leads.
APPLICATION
•Suppression of transients.
DESCRIPTION
The varistors consist of a disc of low-β
ceramic material with two tinned solid
copper leads. They are coated with a
layer of ochre coloured epoxy, which
provides electrical, mechanical and
climatic protection. The
encapsulation is resistant to all
cleaning solvents in accordance with
“IEC 68-2-45”
.
MARKING
The varistors are marked with the
following information:
•Maximum continuous RMS voltage
•Series number (592, 593, 594 or
595)
•Manufacturers logo
•Date of manufacture.
ORDERING INFORMATION
The varistors are available in a
number of packaging options:
•Bulk
•On tape on reel
•On tape in ammopack.
The basic ordering code for each
option is given in Tables 3, 4 and 5.
To complete the catalogue number
and to determine the required
operating parameters, see Table 7.
MOUNTING
The varistors are suitable for
processing on automatic insertion
and cutting and bending equipment.
Varistors with flanged leads provide
better positioning on printed-circuit
boards (PCB) and more accurate
control over component height. This
is important for hand mounting and
automatic insertion techniques;
see Fig.4.
Soldering
≤240 °C; duration ≤5s.
Resistance to heat
≤260 °C; duration ≤5s.
INFLAMMABILITY
The varistors are non-flammable.

Notes to Table 7
1. The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type
selection should be based on multiplying the peak voltage by a factor of 0.707.
2. The voltage measured at 1 mA meets the requirements of
“paragraph 4.3 of CECC specification 42000”
.
3. High energy surges are generally of longer duration. The maximum energy for one pulse of 10 ×1000 µs is given as
a reference for longer duration pulses. This pulse can be characterised by peak current (Ip) and pulse width t2 (virtual
time of half Ip value, following
“IEC 60-2, section 6”
). If Vp is the clamping voltage corresponding to Ip, the energy
absorbed in the varistor is determined by the formula:
where:
K is dependent on the value of t2 when the value of t1 is between 8 µs and 10 µs; see Fig.13.
4. A current wave of 8 ×20 µs (requirement of
“paragraph B.2.10.1 of CECC specification 42000”
) is used as a
standard for pulse current and clamping voltage ratings. The maximum non-repetitive transient current is given for
one pulse applied during the life of the component.
5. Only available on request
6. CECC approved types.
