Thermistors PTC (results: 64)

PTC Thermistors

A PTC thermistor is a type of thermistor in which resistance increases as the temperature rises. It is mainly used to protect various circuits and devices. Our online store offers high-quality PTC thermistors adapted to different operating conditions and the specific requirements of various devices.

PTC Thermistors – Structure and Operation

Both PTC thermistors and other types of these components are very important elements found in many electronic devices. These resistors change their resistance as the temperature changes. In the case of a component such as a PTC thermistor, the resistance increases as the temperature rises. This behavior is the reason for the name of this component. The abbreviation PTC stands for Positive Temperature Coefficient.

Using the properties of a PTC thermistor makes it possible to protect a circuit or device from the negative consequences of a significant increase in temperature. Its operation is therefore similar to the role performed by a fuse. Although PTC thermistors are not as common as some other types of this component, they can still be found in a large number of devices and circuits.

Where Are PTC Thermistors Used?

PTC thermistors are used both by manufacturers of various types of equipment and by electronics enthusiasts who build their own circuits and installations. The function of this component provides a very high level of versatility. A PTC thermistor can therefore be found, for example, in power supplies, where it is used to stop current flow when the values specified by the manufacturer that could endanger the device are reached. This component is also used in refrigerators as an element stabilizing temperature.

A posistor, which is another name for a PTC thermistor, is also used in degaussing coils of CRT displays and in circuits that heat electrodes in fluorescent lamp ballasts. The possibility of using these components in many devices means that the market offers elements suited to various applications. However, for a PTC thermistor to perform its function properly, its parameters must be precisely matched to the requirements of the device.

Where to Buy the Right PTC Thermistor?

Regardless of whether you are looking for a PTC thermistor for a motor or a component for another device, you will certainly find the right product with us. Our assortment also includes other electronic components required for building and servicing equipment. We also offer other thermistors, including the opposite-acting NTC thermistors, which can be used, for example, for temperature measurement.
