2.5G RJ45 Jack with Magnetics Through Hole Connector J11EK1003NLF1（Cross out Magcom RG11881-FE5Q3）

Product Overview

This 2.5G RJ45 jack combines an 8P8C Ethernet interface with an integrated magnetics module compliant with IEEE 802.3bz, supporting data rates up to 2.5GBASE-T. Built with an LCP UL94V-0 black housing and gold plated phosphor bronze contacts, the single port design with 10 pin common mode layout fits routers, switches and NAS devices.

Product Specifications

Product Features

• 2.5G High Speed Support: Integrated magnetics meet IEEE 802.3bz for reliable 2.5GBASE-T data transmission.
• 1500VAC Isolation: Input to output isolation protects PHY circuits from voltage surges.
• Clean Signal Integrity: -30dB crosstalk and common mode rejection keep high speed channels stable.
• Robust Contact Design: Gold plated phosphor bronze contacts ensure low resistance over service life.
• Compact Through-Hole Footprint: Vertical mounting RJ45 Connector saves PCB space in dense equipment.

Packing Details

Each J11EK1003NLF1 unit is packed in anti-static PE bags, placed in protective trays and boxed in standard export cartons. Bulk quantities ship on pallets with desiccant to protect the gold plated contacts and shield during ocean and air transportation.

Applications

• 2.5G Switches: Desktop and enterprise switches with Multi-Gig ports.
• Routers and Gateways: Home and office routers supporting 2.5GBASE-T WAN or LAN.
• NAS Devices: Network storage needing faster than Gigabit links.
• Industrial PCs: Embedded computers with Multi-Gig Ethernet uplinks.
• Smart TVs and Set-Top Boxes: Streaming devices requiring stable high bandwidth connections.

Frequently Asked Questions (FAQ)

Q: What data rates does an RJ45 jack with integrated magnetics support?

A: The J11EK1003NLF1 covers 10BASE-T, 100BASE-TX, 1000BASE-T and 2.5GBASE-T under IEEE 802.3bz. Its insertion loss stays within -0.5 dB up to 50 MHz and -2.0 dB up to 200 MHz, so the magnetics handle every lower Ethernet speed without redesigning the port circuit.

Q: How to design the PCB layout for this through-hole RJ45 magnetic jack?

A: Follow the suggested PCB layout on the drawing, route 100 ohm differential pairs from the PHY to the magnetics center taps, and place the 75 ohm Bob Smith termination network with a 0.1 uF capacitor on the cable side. Keep the vertical through-hole pads matched for symmetric routing.

Q: Does this RJ45 connector include LED indicators?

A: No, the J11EK1003NLF1 is a without LED variant for designs using external status LEDs. If board space or indicator integration matters, LED equipped models in the same J11 family provide green and yellow options with matching electrical performance.
