Strong Overload Capacity High Sensitivity NTC Type Thermistor Easy
To Use
A thermistor is a sensor resistor whose resistance value changes with temperature. According to the temperature coefficient, it is divided into positive temperature coefficient thermistor (PTC thermistor, namely Positive Temperature Coefficient thermistor) and negative temperature coefficient thermistor (NTC thermistor, namely Negative Temperature Coefficient thermistor). The resistance value of the positive temperature coefficient thermistor increases with the increase of temperature, and the resistance value of the negative temperature coefficient thermistor decreases with the increase of temperature. They both belong to semiconductor devices.
A thermistor is a temperature-sensitive protective element. The
thermistor is composed of semiconductor ceramic materials. The
thermistor is made of semiconductor materials, and most of them
have a negative temperature coefficient, that is, the resistance
value decreases with the increase of temperature. Temperature
changes will cause large resistance changes, so it is the most
sensitive temperature sensor. Negative temperature coefficient
thermistor is also called NTC.
Due to these characteristics of the thermistor, the thermistor can
be applied to conversion power supply, switching power supply, USB
power supply, various electric heaters, electronic energy-saving
lamps, electronic ballasts, protection of power circuits of various
electronic devices, and color display tubes. , Filament protection
for incandescent lamps and other lighting fixtures.
The main features of a thermistor are:
① The sensitivity is high, and the temperature coefficient of the
thermistor is 4 to 9 times larger than that of metal;
② Wide operating temperature range, normal temperature devices are
suitable for -55°C ~ 315°C, high temperature devices are suitable
for temperatures higher than 315°C (currently the highest can reach
2000°C), low temperature devices are suitable for -273°C ~ -55°C;
③Small size, capable of measuring the temperature of gaps, cavities
and blood vessels in living organisms that cannot be measured by
other thermometers;
④Easy to use, the resistance value can be arbitrarily selected
between 0.1~100kΩ;

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.
