Design Tools
Models
The varistors consist of a disc of low- ZnO ceramic material
with two solid copper leads (S20 types only) or copper clad
steel wire. The wires have a matte tin plating. They are
coated with UL 94 V-0 approved ocher colored halogen-free
epoxy, which provides electrical, mechanical and climatic
protection.
