varistor from a disc by the halbleitendem zinc oxide material and method of producing the varistors

摘要

The varistor, consisting of a wafer (1), contains in the edge regions of both end surfaces (2, 3) in each case one circumferential step (8, 9) onto which the coating (7) applied to the circumferential surfaces (6, 12) extends, the deposits (4, 5) applied onto the end surfaces (2, 3) at least partially overlapping the parts (10, 11) of the coating (7) which extend onto the steps (8, 9).
