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.

From the appearance, such as a square or round inductor with a magnetic core, slightly larger volume, can see the core and coil.

The chip inductor is only used in the output end of the low-voltage DC control power supply. Its application is seen in the π shape filter circuit of CLC with the filter capacitor, which can stabilize the output current (inhibit current mutation). Inductance components, consisting of a single coil, some with a magnetic core (large inductance), generally expressed in units of μH and mH, current values ranging from a few milliamps to several hundred milliamps.
