1. Spacer for choke and inductor coil

The epoxy glass fiber sheet serves as an insulation spacer for the upper choke.

The common mode inductance is divided into high voltage AC mode and output DC mode. The voltage between the two copper wires determines whether to use the spacer. If the lead string is added and the casing voltage is not high enough, the spacer shall not be added. But considering the consistency, it is more appropriate to have an insulation spacer in bulk production.
