Ceramic PTC
Ceramic PTC thermistor possesses a very low resistance at the room temperature, but its resistance will rapidly jump by 1000 ~ 10000000 of its normal value when its temperature exceeds its Curie point. This characteristic has been widely used in the electronic design for circuit protection. When the heat generated by the through current warms up the thermistor to its curie point, the resistance of the thermistor will considerably increase and this change will protect the circuit from over current damaging. The PTC thermistor will recover when the default is removed.
Applications
For overcurrent protection
For motor start
For degasussing
For heater
