Power NTC Thermistors Resistor
1.Introduction An NTC thermistor has to be connected in series to the power source circuit to avoid the surge current at the instant when the electronic circuits are turned on. The device can effectively suppress the surge current, and its resistance and power consumption can be greatly reduced after that through the continuous effect of the current so as not to affect the normal work current. Therefore the Power NTC thermistor is the most convenient and efficient instrument to curb the surge current and protect the electronic devices from being damaged.
2. Applications Applicable to the protection of the power circuits of conversion power supply, switching power supply, UPS power supply, electric heaters, electronic energy-saving lamps, electronic ballasts and other electronic devices, and the filament protection of color picture tubes, incandescent lamps and other lights.
3.Characteristics: Small size,Strong power and strong capability of surge current protection.
Characteristics Fast response to the rapidly surge.
Big material constant(B value),Small remain resistance.
Longevity of service,High reliability.
Integral series,Extensive operating range.
