Good Stability And Strong Overload Capacity Intelligent PTC Type Thermistor Self Protecting In Case Of Overload

Thermistors are a type of sensitive components, which are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients. A typical feature of a thermistor is that it is sensitive to temperature and exhibits different resistance values at different temperatures. Positive temperature coefficient thermistors (PTC) have larger resistance values at higher temperatures, and negative temperature coefficient thermistors (NTC) have lower resistance values at higher temperatures. They are both semiconductor devices.

Main Feature

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, Wide operating temperature range, normal temperature devices are suitable for - 55°C to 315°C, high temperature The applicable temperature of the device is higher than 315°C (currently the highest can reach 2000°C), and the low temperature device is suitable for -273°C ~ 55°C;
3. Small in size, it can measure the temperature of gaps, cavities and blood vessels in organisms that cannot be measured by other thermometers;
4. It is easy to use, and the resistance value can be arbitrarily selected between 0.1 and 100kΩ;
5. It is easy to process into complex shapes and can be mass-produced;
6. Good stability and strong overload capacity.
