Zenamic is the trademark name of SEMITEC for metal oxide varistors.
Zenamic is the trademark name of SEMITEC for metal oxide varistors. Zenamic exhibits a large non-linear exponent and demonstrates good varistor characteristics that can be approximated as a constant voltage characteristic, making it usable up to high current ranges. It is very ideal as a surge absorber. This product is a ceramic body formed from a powder made primarily of ZnO (zinc oxide) with added additives, which is sintered at temperatures between 1,200 and 1,400°C.
