Actual Size
The HP series metal oxide varistors from UCC/NCC are designed for use in low voltage, high energy
applications. These varistors have a higher energy rating than the H series, while keeping a small
radial package size. When compared to other standard varistors, the HP series allows for a wider
operating temperature range from 40 C up to a maximum of 150 C. An ideal application for these
HP series varistors is in automotive control circuits where very high temperature parts are required.
Refer to the Mini -Glossary at the end of the metal oxide varistors section for additional technical
information and specifications.
