What is the relationship between PTC thermistors and resettable fuses and fuses?
There are two major types of PTC resistors. One is a ceramic PTC resistor. It is a positive temperature coefficient thermistor. It has overcurrent protection, degaussing, heaters, etc., and the other is a polymer organic PTC. This is what you call a resettable fuse. There is a certain difference between the resettable fuse and the ordinary fuse. The resettable fuse can be reused commonly known as the universal fuse. Once the ordinary fuse is burned out, it must be replaced.
PTC heaters are divided according to structural characteristics
(1) Practical PTC ceramic heaters. This type of appliances mainly includes: electric mosquito repellent, hand warmer, dryer, electric hot plate, electric iron, electric iron, electric adhesive, curling iron, etc. The characteristic is that the power is not large, but the thermal efficiency is very practical.
(2) Automatic constant temperature PTC heater. This type of equipment mainly includes: small crystal device constant temperature tank, constant temperature incubator, electronic thermos bottle, thermal insulation box, thermal insulation cup, thermal insulation plate, thermal insulation cabinet, thermal insulation table, etc. It is characterized by automatic insulation, simple structure, good constant temperature characteristics, high thermal efficiency, and a wide range of ambient temperature.
(3) Hot air PTC heater. This type of hot air PTC heater mainly includes: small warm air heater, hair dryer, room heater, dryer, closet, clothes dryer, industrial drying equipment, etc. Its characteristic is output Hot air has high power, fast heating, safety, and can automatically adjust wind temperature and power consumption.
