0402 Series NTC Chip Thermistor Introduction:

NTC thermistor is a kind of ceramic semiconductor heat-sensitive crystal sintered by manganese, cobalt, nickel as raw material, which has high sensitivity to the temperature change, and its zero-power

resistance value decreases with the increase of the body temperature, and the resistance value decreases exponentially with the increase of temperature, and the temperature coefficient is as high as (3~6%/℃), and the small temperature change will cause a big resistance value change. The temperature coefficient is as high as (3~6%/°C), a small change in temperature will cause a large

change in resistance value. According to the R-T resistance temperature curve of the thermistor, the precise resistance value of each temperature point can be measured, and the resistance value can be used in the circuit to realize the digital correspondence of temperature

for temperature measurement and control.

NTC thermistors are widely used

in the fields of home appliances, digital communications, automotive, industrial, medical, etc. because of their advantages of high sensitivity to temperature, good reliability, interchangeability, cheapness, small size, easy to be processed into a variety of desired shapes and sizes, etc. Their main functions are temperature detection and control, temperature compensation, suppression of inrush currents, and fluid flow testing.
