NTC thermistor 5D-13

The function of NTC thermistor is to limit the inrush current that can kill the components in the power section during start up. An NTC thermistor has a relatively high resistance at room temperature, so at turn-on, it limits the current charging the loads rail capacitors. As the thermistor heats up, its resistance drops, so the power supply becomes relatively low impedance. Application: Limiting surge current, suitable for the protection of switch mode power supply, UPS power, various electric heating utensil, energy saving lights, ballast, various power circuit, colored displayer, filament protection, etc; Features Small size, strong power and strong capability of surge current protection Fast response to surge corrent Big material constant(B value), Small remain resistance Longevity of service, High reliability Integral series,extensive operating range
