PT Series –Power Type NTC Thermistor unit：mm PT series 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. FEATURES Strong power and strong capability of surge current protection. Characteristics Fast response to the rapidly surge. Big material constant(B value),Small remain resistance. High reliability. Integral series, Extensive operating range. Operating Temp. -55℃～+200℃ APPLICATION
switching power supply UPS power supply, electric heaters electronic energy-saving lamps filament protection of color tubes incandescent lamps and other lights. electronic ballasts EXSENSE Electronics Technology Co., Ltd.
