A Thermistor is a thermally sensitive resistor whose primary function is to exhibit a change in electrical resistance with a change in body temperature.
NTC thermistor is one in which the zero-power resistance decreases with an increase temperature.
NTC thermistor is one in which the zero-power resistance decreases with an increase temperature.
Features
- Multilayer structure allows diverse resistance value in the same B constant.
- Ultra small size, low capacitor, high B value.
- Glass coated perform for long term reliability.
- Non polarized for mounting.
- Possibility for Flow / Reflow soldering.
- Applications:
- Temperature compensation for crystal oscillator (TCXO).
- Temperature compensation for Personal computer.
- Temperature detection for CPU and memory device.
- Temperature detection for battery pack.
- Temperature compensation for contrast of LCD.
- Temperature compensation and sensing of car audio equipments. (CD, MD, Tuner).
