Why is the smd inductor short-circuited, and what kind of nature will it have after the short-circuit

For smd inductor, under normal circumstances, there will be no short-circuit phenomenon. A large part of the short-circuit phenomenon is due to the high current in the circuit, exceeding the rated current of the smd inductor, and for a long time Work under excessive current conditions.

When the current is too high for a long time, the insulating layer on the surface of the enameled wire of the smd inductor will burn, and then a short circuit will occur.

Once the inductor appears, the physical parameters of the inductor itself will change greatly:

1. The inductor  of the smd inductor will be reduced a lot, and it may not even meet the needs of the circuit. If it is used, there may be risks.

2. The resistance value of the smd inductor will become smaller. Due to the burning of the enameled wire insulation layer, the enameled wires without the insulation layer are in contact with each other, which is equivalent to the contact between the wire and the wire, and the resistance value will naturally become smaller.

After the smd inductor is short-circuited in the circuit, if it is still in operation, the smd inductor will be irreversibly damaged, which will directly cause the circuit to open.

Faced with the problem of short-circuit inductor, Pingshang Technology recommends that customers replace with better quality inductor. The quality of the inductor itself causes short-circuits. Therefore, Pingshang Technology recommends customized inductor products, which are expected to be in a harsh working environment all-weather inductor  products. Can reduce the probability of inductor problems.
