Temperature Sensor NTC thermistor
The term ''Thermistor'' is derived from the description, ''Thermally Sensitive Resistor''. NTC (Negative Temperature Coefficient) thermistors are devices that display a decrease in resistance with an increase in temperature. The ceramic semiconductors and consist mostly of oxidized metal. During the manufacturing process this metal is high temperatures. Thermistors characteristics, resistance values and form factors are determined by the product process and the sensor dimensions. NTC thermistors are commonly used as temperature sensors for a wide of applications requiring temperature measurement and temperature compensation.Jingpu's thermistors are fully compliant with RoHS Directive2011/65/EU.Electrical properties:• Conductor: Conductor resistance at 20ºC: <250 ohm/km NTC chip:• Rmax at -40ºC: 293 kohm.• value: (B25/100)=3988K±3%
