New Energy Special Thermistor MF52A 5K (502) Practical Waterproof Temperature Sensor, Stable Negative Temperature Coeffi
►Different NTC thermistor using in the NTC temperature sensors with the following different operating temperature:
Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual temperature resist grade 150℃
MF58: temperature resist grade 200℃,actual temperature resist grade 250℃
MF51: temperature resist grade 200℃,actual temperature resist grade 250℃
Special MF51: temperature resist grade 250℃,actual temperature resist grade 300℃
Weldless chip:temperature resist grade 450℃,actual temperature resist grade 500℃
►Operating environment
In the environment of high temperature,high humidty and high corrosion,we suggest to use glass sealed type thermistor as the core element.And MF51 type will be the best NTC thermistor in high humidity environment.
►Design considerations and procedure of temperature sensor
1. Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
2. Confirm the thermistor element and other materials according to customers' requirement
3. Choose the suitable resistance,B value and tolerance
4. Choose suitable moisture-proof and insulation technology to meet customer's requirement
5. Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance
6. Meet customer's special requirements.

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
