The grounding plug will lead to self recovery fuse will be burned out?
The problem in the normal self recovery fuse is connected in series in the circuit, overcurrent (including short circuit) when the fever, its resistance suddenly becomes very large (break), short circuit current (fuse removed, return to normal temperature dropped to normal value) after the automatic recovery, the fuse is burned, the ground will not plug burn the fuse.
Self recovery fuse burned may cause overvoltage or quality problems, some self recovery fuse itself quality is not good, such as the electrode itself is not compact, the welding wire, flux and solder into a rosin between the electrode and the ceramic body. The binding force between the electrode and the ceramic body is reduced. The expansion coefficient of the ceramic body, the electrode, the rosin and the solder is not consistent with the stress of the storage environment, which leads to the sealing and cracking of the epoxy resin, and the electrode and the ceramic body are separated, causing damage.
(Introduction of specific specifications for the maximum voltage of self recovery fuse for 30V)
Self recovery fuse is welded on the PCB board, then the problem again, the welding temperature will burn out the fuse?
For this problem, small make up say about it! The components are generally able to withstand the test of temperature, SMT and soldering, if not, will explain the instructions on the device! The welding temperature will burn out the fuse, you this is unfounded.
