Disk NTC Thermistor Resistor NTC 47D-15 47D15 Thermal Resistor 47Ohm 15mm 3A Current Inrush Limited
General Introduction
When you turn 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, so the consumed power can be ignored.Therefore,
using power NTC thermistor
is a most effectively and most brief measure to restrain surge
current,protecting electrical
equipment from destruction.
Application
1.Conversion power-supply, switch power, ups power.
2.Electronic energy saving lamps, electronic ballast and all kinds
of electric heater.
3.All kinds of RT, display.
4.Bulb and other lighting lamps.
Feature
1.Small size, strong power and strong capability of surge current
protection.
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.
