pptc resettable fuse datasheet.There are several general classifications of thermistors
A. Classified by temperature variation characteristics - positive temperature coefficient (PTC), negative positive temperature coefficient thermistors. B. Classified by sensitivity to temperature changes - high sensitivity type (mutation type), low sensitivity type (slow change type) thermistors. C. Classified by heating method - direct heating thermistors, side heating thermistors. D. Classified by structure and shape - various types of thermistors such as circular (sheet), cylindrical (cylindrical), circular (gasket), etc. The most common names for thermistors are PTC thermistors and NTC thermistors. So what is the difference between these two types of thermistors? 1、 PTC thermistor PTC thermistor structure - made from materials such as barium titanate (BaTiO3), strontium (Sr), zirconium (Zr), etc. PTC thermistor characteristics - the resistance value is directly proportional to the temperature change, that is, the resistance value increases as the temperature increases.
