A synchronously switched buck post regulator is revealed for multi-output forward converters. The ceramic filters exhibit a relatively high level of washcoat loading while exhibiting minimized levels of backpressure. The side walls and said horizontal wall together enclose a board segment having a terminal land which is formed at a portion of a printed circuit board and which also is capable of directly contacting the mating connector. In addition, a container that is particularly suitable for the proposed methods and a system with a plurality of such containers are proposed.
