Description:
1.Power Type MF73 Series Black NTC thermistor2.Low cost solid state device
3.for inrush current supressionProductionIntroduction
TheMF72 power NTC thermistor is a kind of semiconductor ceramicelement that mostly made from transition metal oxide material, andbelongs to negative temperature thermistors. When you tune on anelectrical equipment , the surge current can be restrained by apower NTC thermistor connected in series with the power circuit.Because of the continuing action of current, temperature of powerNTC thermistor raising, the resistance will rapidly drop to a smallvalue, the consumed power can be ignored. So it can not affectnormal operating current. Therefore, using power NTC thermistor isa most effectively amd most brief measure to restrain surgecurrent, protecting electrical equipment from destruction.
APPLICATION
Convension power supply , switch power , kinds of electric heater ,electronic energy-saving lamps , electronic ballast etc . All kindsof power circuit protection of electronic equipments , filamentprotection of all kinds of RT , display , bulb and other lightinglamps .
Characteristics
1. Small size , Strong power and strong capability of surge currentprotection.
2. Fast response to surge current.
3. Big material constant(B value), Small remain resistance.
4. Longevity of service, High reliability.
5. Integral series , Extensive operating range
Remark:
1. The Max. Steady State Current meets when the decimal expressedwith three figures.
Other expressed with the actual value.
2.The Rated Zero-power Resistance meets the decimal or is biggerthan is 100Ω when with three expressions, other expressed withtwo.
