Varistors
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 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

ORDERING INFORMATION
MARKING
The varistors are available in a number of packaging options:
The varistors are marked with the following information:
• Maximum continuous RMS voltage
• Series number (592, 593, 594, 595 or 596)
• Manufacturers logo
• 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.
• Date of manufacture.
INFLAMMABILITY
The varistors are non-flammable.
