APPLICATION

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 colored 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.

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
