Subject: [TN] Mini glass beads for ferrite core gapping


Dear Technetters,
Does anyone has successful experience in using mini glass beads for ferrite
core
gapping? We manufacture magnetics for switching mode power supplies and have
gapping problem when using ordinary kapton or polyester tape as gapping
material
between ferrite core because their thickness variation are too high. Any
input
will be highly appreicated. Thanks.

Ken
