1) What is a thermistor?

A thermistor is a device type of resistor whose resistance is dependent on temperature, more so than in standard resistors.
Assuming, that the relationship between resistance and temperature is linear, then:

 


Thermistors can be categorized into two types, depending on the classification of α.
If α is positive, the resistance increases with increasing temperature, and the device is called a Positive Temperature Coefficient(PTC) thermistor.
If α is negative, the resistance decreases with increasing temperature, and the device is called aNegative Temperature Coefficient(NTC) thermistor.


PTC thermistors are used self-resetting overcurrent protectors like a fuse, or are used self-regulating heating elements.
NTC thermistors are used widely as a temperature sensors, or are used inrush current limiter.


NTC thermistor application is widely used for temperature detection of electronic devices and appliances for NTC thermistor function, performance and price reasons.


Mitsubishi Materials' NTC thermistors are manufactured from high purity and uniform materials to achieve a construction of near-perfect theoretical density.


This ensures small size, tight resistance and B-value tolerances, and fast response to temperature variations, making a highly sensitive and precision component.


Thermistor is available in a wide range of types to meet your demands for small size and high reliability.
