The importance of circuit protection


Circuit protection basically protect the component in the circuit from over current, over voltage, OT, TFR and OCOV. The electronic product become more and more complicated and various these days, so as the circuit protection. The circuit protection are basically three types, VDR, TVS and gas discharge tube.

Because of the development of the electronic products, the function of the Integrated Circuits become more and more various. Therefore, we need circuit protection to protect the high function IC.

In order to lengthen the usage life of the products, the working voltage of the semiconductor and IC become lower and lower. Hence, we need new protection to adapt to the new situation.

Mobile devices are enlarging, and they all need battery in it. In the battery we must have a protection.

In the automobile, the electronic devices becomes the absolutely necessary thing. The car use electronic devices to operate. That’s why we need circuit protection to make sure the safety in our driving journey.

Most electronic devices need to avoid the disruption of lighting stroke, power line and telephone wire to make sure normal communicate and the safety of people. The circuit protection become more needed because of this.

By statistic, 75% of electronic breakdown is caused by current and voltage. If we want the product can be competitive with other devices, we need circuit protection.
