NTC Power Thermistor

1.Product introduction:

       In order to avoid the surge current generated in the boot of the moment in an electronic circuit, connected to a power type NTC thermistor in series in the power supply circuit, can effectively inhibit the surge current when starting, and after completion of surge current suppression for later, due to the continuing role of the current, the resistance power type NTC thermistor value will fall to very small degree, the power it consumes negligible, no influence on the normal operating current, so, the use of power type NTC thermistor in the power supply circuit, is to suppress the surge the boot, in order to ensure the most simple and effective measures for the electronic equipment from damage.

2.The scope of application:

       Suitable for switching power supply, switching power supply, UPS power supply, various types of electric heaters, electronic energy-saving lamp, electronic ballast, power electronic circuit protection devices and color display tube, the filament like incandescent lamps and other lighting.

3.Characteristic:

· small volume, large power, strong ability of suppressing surge current

· reaction speed

· material constant (B value), the residual resistance

· long service life, high reliability

· the whole series, wide operating range
