HJ30J High-Speed Micro-D Connectors

100 Ω differential pairs · up to 3.125 Gbps board-to-board

HJ30J brings high-speed differential signals to the Micro-D format. Contacts are arranged as differential pairs with ground contacts between them, for 100 Ω impedance in the same 1.27 mm pitch, twist-pin connector.
