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 solvent.

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. Soldering
