Fuser thermistor manufacturers tell you that a thermistor is a sensor resistor whose resistance value changes with temperature. According to the different temperature coefficients, it is divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors. Fuser thermistor manufacturers tell you that PTC thermistors and NTC thermistors have different functions and applications. This editor will tell you about the application and selection of PTC thermistors.

Application of PTC thermistor in electric heating appliances:
Fan heater, room heater, dryer (cabinet), tumble dryer, hand dryer, hair dryer, hair curler, steam beauty device, rice cooker, mosquito repellent, hand warmer, shoe dryer, pressure cooker, kerosene gasifier , Electric iron, electric soldering iron, plastic welding gun, sealing machine.
Application of PTC thermistor in automobile:
Fuser thermistor manufacturers tell you about electrical overload protection devices, hybrid heaters, low temperature start heaters, fuel heaters, honeycomb heaters, fuel level indicators, engine cooling water temperature gauges.
Selection method of PTC thermistor:
Fuser thermistor manufacturers tell you that each thermistor has parameters such as "withstanding voltage", "withstanding current", "maintaining current" and "action time". You can choose according to the requirements of the specific circuit and the parameters of the product. The specific methods are as follows:
1. The Fuser thermistor manufacturer tells you to first determine the parameters such as the maximum ambient temperature when the protected circuit is working normally, the working current in the circuit, the large voltage that the thermistor needs to withstand after the action and the required action time;
2. Fuser thermistor manufacturers tell you to choose different shapes of thermistors such as "chip type", "radial lead type", "axial lead type" or "surface mount type" according to the characteristics of the protected circuit or product;
3. According to the maximum working voltage, select the product series whose "withstand voltage" level is greater than or equal to the maximum working voltage;
4. According to the large ambient temperature and the working current in the circuit, select the product specification whose "maintenance current" is greater than the working current;
5. The Fuser thermistor manufacturer tells you to confirm that the action time of the thermistor of this specification is less than the time required by the protection circuit;
6. The Fuser thermistor manufacturer tells you to check the data provided in the specification to confirm that the size of the thermistor of this specification meets the requirements.
