HMOV™ Varistor Series

Littelfuse HMOV™ Varistor Series is the first varistor to operate in a maximum ambient temperature of +125°C with 2500V isolation voltage. The Radial Leaded Varistors’ maximum peak surge current is rated up to 10kA (8/20µs pulse). Littelfuse HMOV Varistor Series features a wide operating voltage range and is available in three disk sizes: 10mm, 14mm, and 20mm. HMOV varistors offer protection against indirect lightning strikes, switching surge transients, and abnormally fast transients.
