VDR Metal Oxide Varistors Standard
FEATURES
• Zinc oxide disc, epoxy coated
• Straight leads
• Straight leads with flange (2381 592 and 593
series only)
• Kinked leads
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
• Certified according to UL 1449 edition 3,
VDE/IEC 61051-1/2 and CSA
APPLICATION
• Overvoltage and transient voltage protection
DESCRIPTION
The varistors consist of a disc of low-ß ceramic material with
two tinned solid copper leads or tinned copper clad steel
wire. 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 60068-2-45.

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 outlines of flanged leads
drawing.

ORDERING INFORMATION
The varistors are available in a number of packaging options:
MARKING
• Bulk
• On tape on reel
• On tape in ammopack
The basic ordering code for each option is given in tables
mutitled 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.
The varistors are marked with the following information:
• Maximum continuous RMS voltage
• Series number (592, 593, 594, 595 or 596)
• Manufacturers logo
• Date of manufacture (YYWW)
INFLAMMABILITY
The varistors are non-flammable.
The encapsulation is made of flammable resistant epoxy in
accordance with UL 94 V-0.
