1300500024, also known as PTC (Positive Temperature Coefficient) thermal cutout, is a relatively safe electronic protection device used in power circuits. Because of the inherent material characteristics of ceramics, its working principle is very simple and efficient, so it has been widely used. This article focuses on the application fields and working principles of 1300500024.

Application fields

1300500024 can be widely used in electric appliances, such as household appliances, power tools, lighting control equipment, office equipment, automobiles, consumer electronics and other fields. Most of the time, it is used as an overheat protection device in motors, transformers, power supplies and PCs. With high safety, reliable performance and low price, it has been trusted and favored by many manufacturers.

Working principle

The structure of 1300500024 is made of a metal part and a ceramic component. When the temperature reaches the rated current value, the ceramic component will change its electrical characteristics due to its self-heating. Its internal resistance will rise significantly, and the total resistance of the circuit or the load will rise dramatically, which will stop the current, thus cutting off the power supply.

When the temperature is lower than the rated value, the ceramic component of the device will not be self-heated, so the conductive element is connected, and the load current is normally passed to realize the overload protection. Whenever the overload temperature reaches the rated temperature, the protection switch will be activated, thereby limiting the current output and ensuring safe operation.

Conclusion

1300500024 is widely used in electronic equipment, compared with other electronic protective components, it has the advantages of simple operation and reliable performance, so it is greatly trusted and favored. In addition, its working principle is relatively simple, based on the inherent temperature characteristics of ceramics, it can quickly respond to changes in temperature, so it can play a very good role in temperature control, effectively protecting the safety of electronic equipment.
