Centre potted toroidal transformers

Centre potted transformers can be provided with a drilled central hole (normally 5 to 6 mm), or if the customer prefers, with a threaded hole (normally M3 to M6). In addition to the height of the transformer, approx. 2mm is required for the rubber pad (included).
