Why does the patch inductor short circuit? After short circuit, it will have such a property.
For patch inductors, under normal circumstances, there is no short-circuit phenomenon. The reason for short-circuit phenomenon is that the current in the circuit is too high, which exceeds the rated current of the patch inductor, and works in the condition of too high current for a long time.
When the current is too high for a long time, the insulating layer of the enameled wire surface of the patch inductor will be burned, and then the short circuit will appear.
Once inductance occurs, the physical parameters of inductance will change greatly.
1. The inductance value of the chip inductor will be greatly reduced, even can not meet the needs of the circuit. If used, there may be risks.
2. The resistance value of patch inductance will decrease. Because of the burning of insulating layer of enameled wire, enameled wires without insulating layer contact with each other, which is equivalent to the contact between conductors and conductors, the resistance value will naturally decrease.
After the short circuit of the patch inductor in the circuit, if it is still working, the patch inductor will be irreversibly damaged, which directly leads to circuit breakage.
Patch inductors are seldom short-circuited in conventional use. Once they occur, they indicate that there are problems in the circuit. It is necessary to check the problems in the circuit in order to avoid unnecessary losses.
In the face of the problem of inductance short circuit, GujingElectronics advises customers to replace better quality inductance. It can not be denied that the quality of inductance itself leads to the occurrence of short circuit. For this reason, GujingElectronics recommends customized inductance products, an inductance product expected to be in a bad working environment all day. It can reduce the probability of inductance problems.
