The terminal attachment and resistance element geometry are configured to provide outstanding non-inductive performance. The ceramic substrate is bonded to a copper heat sink which becomes the metal mounting surface. This assembly is molded in a high thermal conductivity molding compound with the copper heat sink flush with the back surface of the part. Certain products shown in this catalog are covered by one or more patents, there are also patents pending.
