Thermistors

Thermistors are a type of resistors whose resistance depends on temperature. The function of these components allows them to be widely used in various electronic devices. Our store provides a wide selection of components, making it easy to find the right part.

What is a thermistor and what is its function?

Thermistors are electronic components characterized by a relatively simple structure. However, they perform a very important function. All beginner electronics enthusiasts who have encountered the graphical symbol of a thermistor but do not know what this component is should certainly understand it. When learning about the structure of various devices, they will certainly encounter it many times. A thermistor is a resistor whose resistance depends on temperature. Although this property actually applies to every resistor, in the case of thermistors it is the main attribute of these elements.

Such functionality of these components is possible thanks to their construction. Thermistors can be manufactured from several different semiconductor powders that are mixed, dried, and protected. The properties of a given component depend on the specific material used. Although the symbol representing a thermistor is the same for every type of this component, the application of its individual types is different.

Temperature measurement with a thermistor and other applications of this component

The most important distinction to remember is the division into PTC and NTC thermistors. Individual types of these components perform different tasks in devices. NTC thermistors are components characterized by the fact that an increase in temperature causes a decrease in their resistance, which enables temperature measurement using a thermistor. This is why this type of component is so widely used by manufacturers of electronic devices. PTC thermistors also perform a very important role. Because their resistance increases as the temperature rises, they can be used as elements that protect a given circuit. The application of components such as thermistors is therefore very broad. That is why it is also worth knowing how to choose a component whose operation will match our expectations.

How to choose the right thermistors?

The parameters of individual components can be checked most easily by browsing the catalog of our online store. The values worth paying attention to are primarily the type of component, its resistance, and its operating voltage. If you are not sure which component will be suitable for your needs, you can also ask our specialists for advice.
