100Mbps RJ45 Magnetic Jack with LED J11GH141NPF1（Cross PULSE J00-0045NL）

Product Overview

100Mbps RJ45 Magnetic Jack with LED J11GH141NPF1 combines an 8P8C receptacle and a transformer module in one shielded through-hole package for 10/100BASE-T Ethernet ports. Built with a high temperature PBT UL94V-0 housing, Gold Flash Plated Contacts on 0.35 mm phosphor bronze terminals and a nickel plated shield, this RJ45 Connector ensures reliable 1500VAC isolation, robust EMI control and dependable LED status indication across demanding networking environments.

Product Specifications

Product Features

• Integrated 100BASE-T Filter: The built-in transformer module with 1 CT : 1 V turns ratio removes external magnetics from the bill of materials and shortens assembly time.
• Green and Yellow LEDs: Dedicated LED pins provide instant link and activity indication without extra board components.
• Gold Flash Plated Contacts: Phosphor bronze terminals with 50 uin nickel underplate and gold flash contact areas keep mating quality stable over repeated plug insertions.
• Robust 1500VAC Isolation: Input to output withstanding voltage of 1500 VAC for 60 seconds plus 1.2 ohm maximum DCR protects sensitive PHY circuitry.
• Flame-Retardant Housing: The high temperature PBT UL94V-0 black body withstands soldering heat and meets the jack cavity geometry of FCC Part 68 Subpart F.

Packing Details

Each J11GH141NPF1 is inspected, packed in anti-static bags and sealed in labeled inner boxes before shipment. Standard export cartons with internal cushioning protect the shield, transformer and through-hole pins during transport. Bulk, tray or tube packing can be arranged to suit manual assembly or automatic insertion equipment. Contact our sales team for carton quantities, current lead times and customized labeling requirements.

Frequently Asked Questions (FAQ)

Q: Does the J11GH141NPF1 include built-in magnetics?

A: Yes. This 100Mbps RJ45 Magnetic Jack with LED integrates a complete 10/100BASE-T transformer module with a 1 CT : 1 V turns ratio, 350 uH minimum open circuit inductance and 1.2 ohm maximum DC resistance, so no external magnetics are required on the PCB.

Q: How much isolation does this RJ45 magnetic jack provide?

A: The transformer withstands 1500 VAC for 60 seconds between input and output, and the design maintains -1.0 dB maximum insertion loss from 0.3 to 100 MHz with -30 dB minimum crosstalk, keeping Ethernet signals stable across the full operating range.

Q: What LEDs are built into this RJ45 Connector?

A: The jack carries a green LED and a yellow LED wired to dedicated indicator pins. They are driven directly from the PHY link and activity outputs through series resistors, giving users immediate visual feedback on link status and network traffic.
