VDR Metal Oxide Varistors Standard

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

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.

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.

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 outlines of flanged leads

drawing.

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.

MARKING

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.
