Application of self recovery fuse in frequency divider

Publisher: Administrator    Date:2020-12-03

The protection requirements of the speaker system are relatively strict. Ordinary fuses only play a one-time protective role in the speaker, which increases the repair rate of the product; in addition, the additional fuse box and wires increase the manufacturer's cost.

In addition, the fuse used must also meet the specifications, and the wrong fuse will damage the speaker. Installing circuit breakers is also a solution; however, they will make noise when they start to disconnect before they are disconnected.

Therefore, the best choice is a resettable fuse. The resettable fuse is equivalent to a soft switch when it is disconnected (in a high-impedance state), and when the fault is eliminated, it will automatically return to the state of a low-impedance path.
