Introduction
The HMOVTM varistor series is specifically designed for applications requiring high surge energy absorption and a high operating temperature of 125°C. With a maximum peak surge current rating of up to 10kA (8/20µs pulse), it provides protection 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 withstand capability up to 10kA (8/20µs pulse)
- Compliant with thermal shock cycling test: -55°C to 125°C, 1000 cycles
- Wide operating voltage range
- Available in three disc sizes: 10mm, 14mm, and 20mm
- Lead-free, halogen-free, and RoHS compliant
Applications
- LED lighting
- Security systems
- Solar inverters
- Automation control
- Power supply units
