Advantage
NTC thermistors are widely used in home appliances, digital communications, automobiles, industry, medical and other fields because of their high sensitivity to temperature, good reliability, strong interchangeability, low cost, small size, and easy processing into various required shapes and sizes. Its main functions are temperature detection and control, temperature compensation, suppression of surge current, fluid flow testing, etc.
Application
Temperature measurement: electronic thermometer, electronic calendar, electronic clock temperature display, electronic gifts, etc;
Temperature control: temperature sensing of rechargeable batteries for mobile phones, car phones, laptops, smart wearable devices and other devices; Temperature compensation: temperature compensation of transistors, ICs and crystal oscillators of mobile communication devices.
Features
1) Small size, no lead, excellent welding performance, suitable for high-density surface mount;
2) The surface of the porcelain body is encapsulated with glass, which has good moisture resistance, high reliability and stability;
3) Wide working temperature range:-40 ℃ ~ 125 ℃;
4) High precision resistance value and B value constant;
5) comply with RoHS environmental standards
Description
NTC thermistor is 1 kind of ceramic semiconductor thermal crystal sintered from manganese, cobalt and nickel as raw materials. It is extremely sensitive to temperature changes. Its zero power resistance value decreases with the increase of body temperature. With the increase of temperature, the resistance value decreases exponentially. The temperature coefficient is as high as (3 ~ 6%/℃). Small temperature changes will cause great changes in resistance value. According to the R-T resistance temperature curve of the thermistor, the accurate resistance value of each temperature point can be measured, and the digital corresponding temperature can be realized by the resistance value in the circuit, which is used for temperature measurement and control.
