Detailed Product Description


Dedicated NTC Temperature Sensor High Sensitivity And Fast Response


Quick detais

•With whole new technology, securing stable performance in long time(annual resistance drift rate ≤1‰).
•Resistance and B value in high precision, with good consistency and interchangeability (precision of resistance and B value reach ±1 % respectively).
•High sensitivity and fast response.
•By using double layer seal technology, featuring fine insulating property and capability to defend against mechanical impact and bending.
•Can be packaged according to installation conditions used for the convenience of user installation.
•Can be made into high dissipation products, in which the test currents are far larger than those in the sensors of traditional structure, making the applied circuits simplified.
Connect the high precision and highly reliable NTC thermistor to PVC conductive wire and enclose it with insulated, heat conducting and water-proof material into the shapes needed for installation and remote temperature measurement and control.
Temperature measurement and control for electromagnetic oven, electric iron, electric hairpin, water heater, water dispenser, warm air blower, dish washer, sterilizing cabinet, washing machine, drying machine, medium and low temperature drying box and thermotank.

Sizes can be customized by request.   


Part number 


HAS—— Special sensors for home appliances.


104 —— Nominal resistance of thermistor, e.g. 104 indicates that the nominal resistance of the thermistor is 10*104 (Ω).


J —— Resistance error (precision) of thermistor, e.g. J indicates the nominal resistance error of the thermistor is ± 5%.


399 —— B25/50 value of thermistor, e.g. 399 indicates the thermistors material factors B25/50 value is 399*10K.


F —— B25/50 error (precision) of thermistor, e.g. F indicates the thermistors B25/50 value (precision) is ±1%.

  Note:R25 precision:F(±1%),G(±2%),H(±3%),J(±5%),K(±10%).
