Inductors with high volts-per-turn
Hi. Does anyone know of a manufacturer making small, low cost off the shelf, inductors designed for withstanding say 400V for 0.5µs repetitively for many years? I am concerned about turn-to-turn breakdown in standard inductors. The ones I have un-wound so far have had the start and finish of the winding overlapping. Manufacturers don't specify the working voltage.
