Tokyo, Japan - NIDEC COPAL ELECTRONICS CORP. released this month, new product of Ceramic PTC Thermistor "CR-CP series" for over current protection, targeting for industrial equipment, information and communication equipment. We have been selling Polymer Resettable Circuit Protector "PRCP series" until now. To meet the requests of long life, we developed a Ceramic PTC Thermistor as product series 　　　　　　　　　　　　　　　　　　　　　 　　　which has capability of operating more than 100,000 times repeatedly. and it has a low operating voltage, low resistance. By reducing the voltage drop due to the decreasing of the resistance value, you can use the protection of low-voltage circuits. By big change in resistance due to an over current during short circuits and motor lock, this product prevents burnout of motor coil, the load of the circuit.
