Disc NTC Thermistor 2.5D-15 2.5 Ohm 15mm 7A Negative Temperature Coefficient Pitch 7.5mm
Production Introduction
The MF72 power NTC thermistor is a kind of semiconductor ceramic
element that mostly made from transition metal oxide material, and
belongs to negative temperature thermistors. When you tune on an
electrical equipment ,the surge current can be restrained by a
power NTC thermistor connected in series with the power circuit
.Because of the continuing action of current, temperature of power
NTC thermistor raising, the resistance will rapidly drop to a small
value, the consumed power can be ignored. So it can not affect
normal operating current. Therefore, using power NTC thermistor is
a most effectively amd most brief measure to restrain surge
current, protecting electrical equipment from destruction.
APPLICATION
Convension power supply , switch power , kinds of electric heater ,
electronic energy-saving lamps , electronic ballast etc . All kinds
of power circuit protection of electronic equipments , filament
protection of all kinds of RT , display , bulb and other lighting
lamps .

How To Select an Inrush Current Limiter(NTC Thermistor)
Choosing the correct inrush current limiter for your inrush current
limiting needs can be vital for any project. Aolittel’s NTC inrush
current limiters are designed to protect your components from
damaging levels of inrush current at startup.
Below you will find information about measurements you will need to
select the right inrush current limiter for your projects,
calculators to help determine these values, and information about
our NTC inrush current limiter lines and other useful content.
