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.
