The shielded body with EMI fingers provides a continuous ground path from the connector shell to the panel, which matters for keeping radiated emissions under control in industrial and telecom equipment. The Cat5 rating means this jack supports 100 MHz signaling — sufficient for 100BASE-TX and standard Ethernet, but not rated for the higher frequencies of Cat6 or Cat6a.
Board Layout and Termination Notes
Right-angle orientation with tab direction up means the jack loads from the top edge of the PCB — the footprint keeps the port openings parallel to the board surface. Through-hole solder tails give better mechanical retention than SMT on a connector that sees cable insertion force repeatedly.
