Small Size And Fast Response Power NTC Thermistor Working
Temperature Range Is Wide
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.
Applications:
Can be installed into the power circuits of:
• Power supplies and inverters
• Uninterruptible Power Supplies
• Energy saving lamps
• Electronic Ballasts
• Filament Protection of various types of lamps
• Some types of heaters
• For higher power circuits ask about the MF73
and MF74 series surge suppressors.

Negative temperature coefficient thermistor, also known as NTC
thermistor, is a kind of sensor resistance whose resistance value
decreases with the increase of temperature. Widely used in various
electronic components, such as temperature sensors, resettable
fuses and self-adjusting heaters, etc.
