The RB1-125BTAGA is an integrated magnetic RJ45 jack (Magjack) supporting 10/100 Base-T Ethernet communication.
This 1x1 port RJ45 Magjack integrates an Ethernet connector with built-in magnetic components, eliminating the need for external LAN transformers and simplifying PCB design. Featuring a tab-down through-hole PCB mounting structure, integrated green and yellow LED indicators, and a shielded housing design, RB1-125BTAGA provides reliable Ethernet connectivity for network equipment, industrial controllers, embedded systems, and communication devices.
Unlike standard RJ45 connectors, a magnetic RJ45 connector combines the RJ45 interface and Ethernet isolation transformer into one compact component. This integrated design helps engineers reduce PCB space, simplify layout complexity, and improve Ethernet system reliability.
