The HMOV™ 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.

 Features:

  • High operating temperature combined with high isolation voltage capability: 125°C and 2500V, respectively
  • High surge current withstanding capability up to 10kA (8/20μs pulse)
  • Complies with 1000 cycle, -55°C to 125°C, Thermal Shock Cycling Test
  • Wide operating voltage range
  • Three disc sizes available: 10mm, 14mm, and 20mm
  • Lead-free, Halogen-free, and RoHS compliant

Applications:

  • Industrial Automation Controls
  • Solar Power Inverters
  • Security Systems
  • Fire Alarm and Smoke Detectors
  • LED Lighting
  • Base Transceiver Station (BTS) Power Supplies
  • Harsh Environment/Outdoor Power Supplies
