PTC (positive temperature coefficient) resettable fuses are a type of fuse with high reliability, stable performance, and long life which are widely applied in various fields. PTR060V0090-BK1 is a common model of PTC resettable fuses developed by a Chinese brand. Developed with advanced technology and premium material, the resettable fuse features in high operating temperature and over-current protection performance. It is widely applied in many aspects and performs excellently.

The application field of PTR060V0090-BK1 is quite extensive. Firstly, it is widely applied in the durability testing of motor, transformer, wire harness, etc. Secondly, it works as safety protection in the entertainment & automation equipment, such as game consoles, film equipment, staging light equipment, roller coaster, etc. Thirdly, it is used for over-charging and over-current protection in digital products, such as digital cameras, mobile phones, tablets, PC and routers. Finally, it also can be utilized in the sensor, new energy, battery and electronic appliance to improve the product performance or ensure the safety of use.

Working Principle of PTR060V0090-BK1: In simple words, the working principle of the PTC resettable fuse includes three parts—detection, electricity protection and over-heat protection. Firstly, when the current over the rated value, the internal temperature of the fuse will rise, and the fuse would feels like a piece of solid-state “integrity”. Secondly, when the current exceeds a certain value, the material inside the fuse will generate its characteristic “resolve” electricity conductivity, which avoids the overload current further damaging in the circuit and greatly improves the reliability of the circuit. Finally, when the excess temperature and over-current occur simultaneously, PTR060V0090-BK1 will heat instantly and disconnect the circuit automatically which effectively protect the equipment from destruction.

In conclusion, PTR060V0090-BK1, developed by a Chinese brand, belongs to the PTC resettable fuse category. It has high operating temperature and over-current protection performance, and is widely applied in a number of aspects, including motor, transformer, wire harness, entertainment & automation equipment, digital products, sensor, new energy, battery and electronic appliance. Its internal working principle includes three parts—detection, electricity protection and over-heat protection—which all contribute to improving the product performance as well as ensuring the safety of use.
