Hello All, I received some transformer samples for a modem front end circuit that are supposed to have been designed to UL1950 and IEC950 creepage dimensions. It appears that the spacings would be correct if the core material was not considered. I believe this to be an oversight made by the transformer designer.
Is the ferrite core considered a conductive material? If so, do the primary-secondary distances apply to each winding and the core material? Thanks in advance, Rich Kalian Aware, Inc. [email protected]
