6. Response quickly to and highly sensitive to thermal sensation.

NSP power type thermistor
A surge current of a remarkable value will occur with no doubt at the brief moment when the current is key-on in an electronic circuit incorporating capacitors,heaters or motors. The peak value of this surge current can be very high although the surge current only works for a short time.The surge current can be as higher as 100 times the working current in a converting power,switch power or a UPS power, so there must be an efficient way to bring down this surge current. A NTC thermistor of NSP Power-type is a semi-conductive ceramic component made from a transitional metal oxide as a major material, and is classified under the category of negative temperature thermistors.When a current is applied directly to a NTC thermistor of power-type, the resistance goes down in response as the thermistor is heating up. Thanks to the pre-set Zero-power resistance of the NTC thermistor of power-type,it can be bring down effectively the surge current while it is connected in parallel in the power loop. Besides, the constant impact produced by the passing current makes the resistance of a NTC thermistor of power-type go down to its minimum after the bring-down is completed. Its power dissipation is ignorable since it produces no impact to the normal working current. Here comes the conclusion: to bring down the turn-on surge current and thus keep safe of your electronic devices,the simplest and the most efficient way is to equip the power loop with a NTC thermistor of NSP power-type.

* Application
Converting power, switch power, UPS power, electric heating devices of all types, electronic energy-saving lamps, electronic ballasts, power circuits of electronic appliances of all kinds, color picture tubes, incandescent bulbs and other illuminating lamps.
