Murata POSISTOR PTC thermistors employ elements based on ceramics (featuring) good reliability and performance. The diverse product range not only includes different shapes (SMD chip and lead types), but also covers diverse applications such as overcurrent protection, overheat sensing, and inrush current suppression.

Immersion heaters once only used resistance wire, but modern heaters can use Positive Temperature Coefficient (PTC) chips as the heat source. These ceramic chips offer various resistant qualities and when properly used, they can stop your system from overheating—this is a huge benefit for any users of wet process heating methods.

Vishay Intertechnology’s PTC (positive temperature coefficient) thermistors portfolio includes parts for over-temperature protection, overload protection, heating applications, and time delay for lighting; motor start packages; motor start pellets; and nickel film linear thermistors.

This temperature sensing circuit uses a resistor in series with a positive–temperature–coefficient (PTC) thermistor to form a voltage–divider, which has the effect of producing an output voltage that is linear over temperature.

Exploiting the PTC characteristic (a sharp increase in resistance above a certain temperature), the PRF series chip PTC thermistors are used for overheat sensing in FETs, power ICs, and other heat generating areas.

PTC thermistor or PTC chip is the heart of all our PTC range heaters, below are some of our standard PTC thermistors available for direct purchase: Rectangle Type | Disc Type. What is a PTC Heating Element?

Like NTC thermistors, PTC thermistors can be used as temperature sensors by utilizing the change in resistance due to changes in temperature. It is characterized by being able to detect when the device is hot with a very simple circuit configuration.

Apr 10, 2024 · PTC thermistors are resettable devices that return to their original low-resistance state once the temperature decreases below the threshold level. This allows them to provide overcurrent protection repeatedly without needing replacement.

Commercial switching PTC thermistors are manu-factured much like the NTC disk and chip type thermistors with metallized surface contacts. Connection into an electrical circuit is accomplished by means of a spring contact system or through lead wires soldered to the device.

Mar 5, 2019 · PTC heaters improve on previous heater designs to provide safe, energy-efficient heating systems for applications large and small. Understanding the benefits to these heaters over traditional coil or ceramic chip options can help …
