Part Details

The completed prototype consists of a windings assembly and two core halves,
as shown in Figure 1. The windings assembly is a combination of Primary Boards,
Secondary Stamps, Insulator Washers, and if needed, an Auxiliary Board.
Figure 1. Major Components of a Planar Transformer
Each design requires a unique number of boards and stamps. The number
and orientation of the boards and stamps are dependent on the turn counts
and required DCR rating.
An insulator washer is used between each part of the windings assembly and
between the windings assembly and each core half.
