HMOV Varistor Series
Description
The HMOVTM Varistor Series is specifically designed for
applications requiring high surge energy absorption and high
operating temperature of 125°C.
The maximum peak surge current is rated up to 10kA
(8/20µs pulse) to protect against indirect lightning strikes,
switching surge transients, and abnormally fast transients.
