Vishay / Ametherm CL20 Ceramic PTC Thermistors
Vishay / Ametherm CL20 Ceramic PTC Thermistors deliver voltage ratings up to 750V and maximum energy ratings to 700J. This Vishay / Ametherm PTC thermistor series offers four resistance values from 7.0 to 100Ω at +25°C to accommodate a variety of pre-charge times. These resistance values of the CL20 remain unchanged over the typical operating temperature range of -40°C to +110°C. CL20 thermistors provide high reliability and stability in high-voltage applications and can withstand hundreds of hits of maximum inrush current without degrading.
