Small Size Strong Power 5D-20 NTC Thermistor Strong Capability Of
Surge Current Protection
The characteristics of the thermistor are as follows:
1) High sensitivity, its temperature coefficient of resistance is
10 to 100 times larger than that of metal, and can detect
temperature changes of 10-6°C;
2) The working temperature range is wide, the normal temperature
device is suitable for -55°C ~ 315°C, the high temperature device
is suitable for a temperature higher than 315°C (currently the
highest can reach 2000°C), and the low temperature device is
suitable for -273°C ~ -55°C;
3) It is small in size and can measure the temperature of gaps,
cavities and blood vessels in living organisms that cannot be
measured by other thermometers;
4) Easy to use, the resistance value can be arbitrarily selected
between 0.1 ~ 100kΩ;
5) It is easy to process into complex shapes and can be
mass-produced;
6) Good stability and strong overload capacity.
working principle
The thermistor will be in a non-action state for a long time; when
the ambient temperature and current are in the c zone, the heat
dissipation power of the thermistor is close to the heating power,
so it may or may not act. When the ambient temperature is the same,
the operating time of the thermistor shortens sharply with the
increase of the current; when the ambient temperature is relatively
high, the thermistor has a shorter operating time and a smaller
holding current and operating current.

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.
