The RJ45 connector. Ethernet design guidelines state that there must be a 1:1 isolation transformer between the cable and the PHY. These are known as the magnetics.. The TE Mag45 connector. Ethernet transformers are surprisingly expensive in small quantities so in my design I’ve chosen the TE 6605424 1 connector that integrates the magnetics and an ESD protection circuit into the connector.Apple iPhone charger teardown: quality in a tiny expensive ...
