Shielded RJ45 Jack for Cat5 Networks
The vertical orientation and through-hole solder termination suit it for PCB mounting where the cable enters from above the board, typical in wall plates, patch panels, and industrial Ethernet endpoints. The shielded shell bleeds EMI to the board ground before it reaches the signal pairs, which matters when the jack lives near switching supplies or motor drives. The thermoplastic housing carries a board guide to align the connector during hand assembly or wave solder.
Cat5 Rating and What It Covers
The Cat5 rating guarantees the jack's electrical performance up to 100 MHz, sufficient for 100BASE-TX and 1000BASE-T Ethernet at the full 100-meter channel length. The shielded construction helps maintain the near-end crosstalk (NEXT) and return loss margins that Cat5 certification requires, especially in electrically noisy environments where an unshielded jack would let common-mode noise couple into the pair.
