MZ11-20P3R7H265 3R7 Ohm PTC Thermal Resistor , LED Positive Thermal Coefficient Thermistor

PTC is the abbreviation of Positive Temperature Coefficient, which means a positive temperature coefficient, and generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually the PTC we refer to refers to the positive temperature coefficient thermistor, referred to as the PTC thermistor. PTC thermistor is a typical temperature-sensitive semiconductor resistor. When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature.
A type of thermistor, the resistance value of the positive temperature coefficient thermistor shows a stepwise increase with the increase of the temperature of the PTC thermistor body. The higher the temperature, the greater the resistance value.

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;
PTC thermistor
2. The working temperature range is wide, the normal temperature device is suitable for - 55 ℃ ~ 315 ℃, the high temperature device is suitable for a temperature higher than 315 ℃ (currently the highest can reach 2000 ℃), and the low temperature device is suitable for - 273 ℃ ~ 55 ℃;
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 ~ 100kΩ;
5. It is easy to process into complex shapes and can be mass-produced;
6. Good stability and strong overload capacity.

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.
