Product Description
CWF5 Silicone Slot Assemble NTC Sensor For Lithium Battery Temperature Control Module
Description
Thermistor is a ceramic semiconducting element made from exorbitant oxides material. It
has the feature that the resistance changes according to the ambient temperature.Namely,
their resistance declines with the rising of ambient temperature at a determinate measuring
power.With this feature NTC thermistor and temperature sensor can be applied in the
situation of temperature measurement and control,compensation and surge current protection.

(Highest tolerance can be reach ±0.02℃) (Years of drif rate ≤1‰)
Operating temperature and environment of NTC temperature sensor depend on specific performance of its core element and lead wire:
►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.
