Thermistors are part of our temperature range of products; they are a very small in size and an accurate way of measuring temperature.
There are different types of thermistors which suit different applications.
The main two types of thermistors are NTC (Negative Temperature Coefficient) and PTC (Positive temperature coefficient). Thermistors measure temperature by using resistance.
With an NTC thermistor, as the temperature increases the resistance decreases, and when the temperature decreases, the resistance increases. NTC thermistors are the most common types of thermistors. With a PTC thermistor; the temperature will increase and decrease with the resistance.
Thermistors will often be described using their resistance value; for example a 10K thermistor or a 5K thermistor etc. This number represents the resistance value in Ohms. We have displayed our thermistors on our website by resistance value as it is a common feature to determine which thermistor is best for applications.
Thermistors have different styles; the most common two are radial or axial. Radial thermistors have both wires leaving the bead in the same direction. Axial thermistors have one wire coming out of the top and one at the bottom with the thermistor bead in the middle. Thermistor chips have no leads.
The beads of thermistors are usually made out of either glass or epoxy. Epoxy thermistors are more suited to lower temperature applications whereas glass thermistors are usually used for higher temperature applications.
Because they are small in size, highly accurate and usually very good value for money, thermistors are widely used for temperature measurement. Some of the industries which use thermistors are;
