Description:

1. 100% brand new and high-quality products.

2. Made of high-quality materials, durable and practical.

3. NTC thermistor is a kind of thermal ceramic component made of electronic ceramic technology with transition metal oxide as the main raw material.

4. Its resistance value decreases with increasing temperature. This feature can be used to make temperature measurement, temperature compensation and temperature control components, and can also be made into power-type components to suppress the surge current of the circuit. This is because the NTC thermistor has a rated zero-power resistance value. When it is connected in series in the power circuit, it can effectively suppress the startup surge current. And after the effect of suppressing the surge current is completed, the resistance value of the NTC thermistor is reduced to a very small extent by the continuous action of the current)

 

5. NTC is the abbreviation of Negative Temperature Coefficient in English. Its meaning is negative temperature coefficient.

6. NTC thermistors have different resistance and temperature characteristics according to different materials and processes.

 

NTC thermistor parameter introduction:

The nominal resistance value is the resistance value designed by the NTC thermistor, which is often marked on the surface of the thermistor. The nominal resistance value refers to the zero power resistance value when the reference temperature is 25°C, so it is also called the resistance value R25.

 

Rated power refers to the allowable power dissipation of the thermistor under long-term continuous load under the atmospheric conditions of an ambient temperature of 25°C, a relative humidity of 45% to 80%, and an atmospheric pressure of 0.87 to 1.07Pa.

 

Measure the resistance value of the thermistor at the specified temperature. When the resistance value change caused by the internal heating of the resistor is relative to the total measurement error, the measured resistance value can be ignored.

 

The temperature coefficient of resistance refers to the relative change in the resistance value of the thermistor when the ambient temperature changes by 1°C. After knowing the resistance temperature coefficient of a certain type of thermistor, the actual resistance value of the thermistor at the corresponding temperature can be estimated.
