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

1. Zero-power resistance (R*5) : the measured resistance of power NTC thermistor under the condition of *5C with a rated zero-power .
2. 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)

1. Power NTC thermistors are in small size but with a high power that to restrain the surge current .
2. Powe NTC thermistors possesse the electronic character of fast reflection ,high reliability and long-life time for use.
3. The material has a high constant as B value with small remained resistance .
4. Power NTC thermistors have a large application range integrate products series .
