NTC 47D-15 THERMAL RESISTOR
₹20.00
The 47D-15 Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a 47D-15 in series with the power source will limit the current surges typically created at turn on. Once the circuit is energized the resistance of the 47D-15 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current. Using the 47D-15 Power NTC Thermistor is a most cost-effective way to curb surge current and protect sensitive electronics from damage.
Rt Resistance Value at Zero-power:
-
- It’s a resistance which is got at a fixed temperature on a basis of a testing power which causes resistance to Vary in a range which can be ignored in relation to the total testing eror.
R25 Resistance Value at Rated Zero-power:
-
- The design resistance of the thermistor usually refers to the resistance value got at Zero-power at 25℃ which is usually indicated on the thermistor.
Max. steady state current.Imax:
-
- The maximum allowable continuous current passing through thermistor at 25℃.
Dissipation Coefficient δ:
-
- It’s the ratio of the changes with a thermistor dissipation power, in a pre-set ambient temperature, to the changes with the temperature. The formula is as below:δ = △P/△ T ,δ changes in response when the ambient temperature changes, within the ranges of the working temperature.
Application:
-
- Conversion power supply, switch power, UPS power, Kinds of electric heter, electronic energy-saving lamps, electronic ballast etc all kinds of power cicuit proterction of electronic equipments, filament proterction of CRT, bulb and other lighting lamps.
Package Includes:
-
- 1 x NTC 47D-15 Thermal Resistor
