The H series metal oxide varistors from UCC/NCC are designed for use in low voltage, high energy
applications such as automotive. These varistors have a much higher energy rating when compared
to the general purpose G series. The H series varistors have a standard varistor voltage tolerance of
10% and a wide operating temperature range of 40 C to 125 C.
Refer to the Mini -Glossary at the end of the metal oxide varistors section for additional technical
information and specifications.
