Product Description
NTC thermistor
1.Power NTC thermistor introduction
Power NTC thermistor has en excellent non-linearity characteristic for the resistance and temperature ,its appliance is an easy and effective method to protect electronic device through surge current restraining .
2.Resistance and temperature characteristic of power NTC thermistor
Power NTC thermistor can effectively restrain the surge current in the circuit ,and its resistance will fall down to a very small state through the current durative and the power consumption is commonly ignored , the coltage will be borne by the rear divice so that to guarantee the normal function of circuit .
The intergradations metal oxide as the main material , power NTC thermistor is a kind of semi-conductive component manufactured by the ceramic productive process technique ,it belongs to the category of negative thermistor series .
3.Range of application
Power NTC thermistor are widely applied in switch power ,conversion power supply ,UPS power and electronic rectifier ,heater ,etc , it has a protected function for RT ,display ,lighting device and circuit of different electronic equipments .
4.Nomenclature explanation
Zero-power resistance (R25) : the measured resistance of power NTC thermistor under the condition of 25C with a rated zero-power .
The maximum steady current (Imax):the maximum current that could be allowed connecting with the power NTC thermistor under the rated current condition (virtual value)
5.Characteristic of power NTC thermistor
Power NTC thermistors are in small size but with a high power that to restrain the surge current .
Powe NTC thermistors possesse the electronic character of fast reflection ,high reliability and long-life time for use.
The material has a high constant as B value with small remained resistance .
Power NTC thermistors have a large application range integrate products series .
