74990101210 10/100 Base-T Vertical RJ45 MagJack Green/Yellow LED

Description of 74990101210 Vertical RJ45 Jack:

The 74990101210 WE-RJ45 LAN transformer is a single-port 10/100BASE-T Ethernet RJ45 connector with integrated magnetics, designed for reliable Fast Ethernet connectivity in networking equipment. It features a vertical THT mounting design, non-PoE configuration, and integrated current and voltage magnetics to ensure proper signal coupling, EMI suppression, and electrical isolation between the Ethernet PHY and the network cable.

The Magjack operates across an extended temperature range of −40 °C to +85 °C, making it suitable for industrial Ethernet devices, routers, switches, and embedded networking systems. It also includes green-yellow LED indicators for link and activity status, enabling easy network diagnostics and monitoring.

Functions and Features of 74990101210 WE‑RJ45

1. Integrated LAN Magnetics
The 74990101210 integrates Ethernet transformer magnetics directly inside the RJ45 connector, providing signal isolation, impedance matching, and noise suppression between the Ethernet PHY and the network cable.

2. Supports 10/100BASE-T Fast Ethernet
Designed for 10/100 Mbps Ethernet communication, ensuring stable data transmission over standard twisted-pair copper cables such as Cat5 or Cat5e.

3. Industrial Temperature Range
Operating temperature from −40 °C to +85 °C, making the connector suitable for industrial networking equipment and harsh environments.

4. Vertical Through-Hole Mounting (THT)
The vertical PCB mounting design with through-hole technology provides strong mechanical stability and reliable soldering for networking hardware.

5. Integrated Link and Activity LEDs
Includes green-yellow LED indicators that provide clear visual feedback for link status and network activity, helping engineers quickly diagnose connection conditions.

6. Non-PoE Design
Optimized for standard Ethernet applications without Power over Ethernet, simplifying circuit design and improving reliability in non-PoE systems.

7. EMI and Signal Integrity Optimization
Integrated magnetics help reduce electromagnetic interference (EMI) and maintain high signal integrity, ensuring consistent network performance.
