PTC Resettable Fuses

TRF250-080T Application Field and Working Principle

Polymer positive temperature coefficient (PTC) resettable fuses, also known as thermally protected polymer positive temperature coefficient, are safety devices with certain over current protection functions. It is mainly used in the electrical circuits, automotive electronics, industrial, communications, household appliances, toys, hazardous and explosive protective circuits and other fields.

A TRF250-080T PTC resettable fuse is a typical PTC device that is used in automotive, industrial, and consumer applications. The device is based on PT Polymer positive temperature coefficient technology and protects all circuits that are subjected to high current and short-circuit conditions. The TRF250-080T resettable fuse eliminates the need for multiple fuses in a circuit. It is a device that can withstand up to 250V and 0.8A of current.

The working principle of the TRF250-080T resettable fuse is simple: when an overload occurs, the TRF250-080T will heat up and open the circuit, cutting off the current flow. When the temperature of the resettable fuse drops to a certain level (the reset temperature), the circuit will automatically be restored and the resettable fuse will again allow current to flow through the circuit. In the event of a short circuit, the current flow will be blocked and the circuit will be shut down, thus preventing damages to electronic components.

The TRF250-080T PTC resettable fuse is a self-recovering electronic protection device with no need for manual resetting or replacement. It is made of PTC polymer material, which is very resistant to high temperatures and has excellent current-limiting characteristics. The TRF250-080T can be used in a wide range of applications, including automotive, industrial, and consumer applications, as it is designed to be waterproof, dust-proof, and vibration-proof.

The TRF250-080T PTC resettable fuse is an effective device for providing circuit protection from short circuits and overcurrent. The device is designed to provide circuit protection while maintaining a low cost and making fewer design changes. In addition, its self-recovery function eliminates the need for manual resetting and makes it a reliable and cost-effective solution in circuit protection.
