The fault substitution of the SMD inductor
The fault substitution of the SMD inductor is as follows.
1) The same type of components can be replaced from the scrap circuit board.
2) First determine the inductance and current value, replace it with an ordinary inductor with a pin, and fix it well.
3) Self-winding, making inductance substitute, there is a certain difficulty in operation.
4) If there is no obvious impact on circuit performance, emergency repair can be temporarily short-circuited (for reference only, this repair method is not recommended, and may reduce some performance of the product).
