Manganese core inductors without base
This non-base coil inductor carries a spacer in the middle, which can effectively improve the voltage resistance of the coil inductor.
This inductor has a yellow tape wrapped around the surface and a sleeve wrapped around the pins, which provides good insulation properties.
The next inductor is a non-base coil, which has appeared many times in previous literature. The non-base inductor has a special mounting method, which can be either a conventional plug-in or a flat mounting method similar to chip inductors.
