CL20 Series – PTC Thermistor Inrush Current Limiter

The CL20 Series of PTC thermistors provides stability and reliability in high-voltage applicationsThis series of ceramic PTC circuit protection thermistors combine the industry’s highest voltage rating with lowest available resistance. They also provide an alternative to fixed resistors and are optimized for inrush current limiting and over-current protection in precharge circuits and heater applications.

The CL20 Series deliver voltage ratings up to 1200 VDC and maximum energy ratings up to 600 J. The thermistors offer five resistance values at 25 °C from 7.0 W to 100.0 W — with tolerance down to 25% — to accommodate a variety of precharge times. These resistance values remain unchanged over the operating temperature range of -40 °C to +110 °C.

The CL20 Series of PTC thermistors provides stability and reliability in high-voltage applications, and also can withstand hundreds of hits of maximum inrush current without degrading.
