DESCRIPTION
The varistors consist of a disc of low-ß ceramic material with
two solid copper leads (H20 types only) or copper clad steel
wire. The wires have a matte tin plating. They are coated
with a layer of ocher colored halogen- free epoxy, which
provides electrical, mechanical and climatic protection. The
encapsulation is resistant to all cleaning solvents in
accordance with IEC 60068-2-45.
MOUNTING
The varistors are suitable for processing on automatic
insertion, cutting and bending equipment.
Typical Soldering
235 °C, duration: 5 s (Pb-bearing)
245 °C, duration: 5 s (lead (Pb)-free)
Resistance to Soldering Heat
260 °C; duration: 10 s max.
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
titled Varistors on Tape on Reel, Varistors on Tape in
Ammopack, and Varistors in Bulk. To complete the catalog
number and to determine the required operating
parameters, see Electrical Data and Ordering Information
table.
Note
• Special lead-configuration as inside or outside crimped leads on
request.
MARKING
The varistors are marked with the following information:
• Maximum continuous RMS voltage with - E suffix
• Series number (582, 583, 584, 585 or 586)
• Manufacture logo
• Date of manufacture (YYWW)
• Safety marks on VDRH10-14-20 types
INFLAMMABILITY
The varistors are passive non-flammable. The encapsulation
is made of flame resistant epoxy in accordance with
UL 94 V-0.

Notes
(1)
The products are certified according to (c)UL (E332800), VDE (40013495), and CSA (219883)
(2)
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.
(3)
The voltage measured at 1 mA meets the requirements of IEC 61051.
The tolerance on the voltage at 1 mA is ± 10 %.
(4)
High energy surges are generally of longer duration. The maximum energy for one pulse of 10 x 1000 μs is given as a reference for longer
duration pulses. This pulse can be characterised by peak current (I
p
) and pulse width t
2
(virtual time of half I
p
value, following “IEC 60060-2,
section 6“). If Vp is the clamping voltage corresponding to I
p
, the energy absorbed in the varistor is determined by the formula:
E
=
K x V
p
x I
p
x t
2
where K is dependent on the value of t
2
(see Peak Current as a Function of Pulse Width drawing).
(5)
A current wave of 8 x 20 μs 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.
(6)
For composition of the SAP part number:
Replace “x” by B for bulk type
Replace “y” by S for straight leads
T for tape and reel
K for kinked leads (bulk only)
A for tape and ammopack
L
for kinked leads with H0 = 16 mm (tape and reel/ammo)
M for kinked leads with H0 = 18.25 mm (tape and reel/ammo)
(7)
All varistors are recognized under VZAC2/VZCA8 surge protective devices, components type 4 as specified in UL 1449 edition 3 for
operating temperatures up to 85 °C. The parts with indication type 2 or 3 SPD’s, are tested and certified to be used in type 2 or 3 SPD
applications for operating temperatures up to 85 °C. The parts with indication type 5 SPD, are tested and certified for operation up to
105 °C ambient temperature for use in type 2 SPD applications with nominal discharge current of 3 kA. The final acceptance of the
component is dependent upon its installation and use in complete equipment submitted to underwriters laboratories Inc.
