1) What is a thermistor?

A thermistor is a type of resistor whose resistance changes with temperature changes.
Assuming the relationship between resistance and temperature is linear, then:

 


Thermistors can be categorized into two types based on their α.
If α is positive, resistance increases with increasing temperature and is called a Positive Temperature Coefficient (PTC) thermistor.
If α is negative, resistance decreases with increasing temperature and is called a Negative Temperature Coefficient (NTC) thermistor.


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


NTC thermistors are widely used for measuring temperature in electronic devices and appliances because of their function, performance, and price.


Mitsubishi Materials NTC thermistors are manufactured using very pure and uniform materials with a nearly perfect theoretical density.


This ensures small size, precise resistance, and B value tolerance which can quickly respond to temperature changes, making them highly sensitive and precise components.


These are available in a wide range of sizes and resistances to meet your requirements for small size and high accuracy.
