100Base-T RJ45 Magnetic Jack with LEDs Ethernet Connector J11VH5153NPF1（Cross WE 74990101210 ）

Product Overview

The J11VH5153NPF1 is a single port 100Base-T RJ45 magnetic jack with LEDs for link and activity status. The integrated transformer provides a 1:1 Plus or Minus 3% turns ratio and 350uH minimum open circuit inductance, while 1500VAC input to output isolation protects host electronics. Gold plated contacts over a 50u nickel underplate ensure durable mating, and the FCC Part 68 compliant cavity suits general purpose LAN equipment.

Product Specifications

Product Features

• Integrated 10/100Base-T Magnetics: The built-in transformer saves board space and keeps the 1:1 turns ratio within 3% across the operating range.
• Dual Color LED Indicators: A green LED and a green yellow LED provide link and activity status directly on the port.
• Gold Plated Contacts: 6u gold over a 50u nickel underplate on phosphor bronze contacts resists wear and oxidation.
• 1500VAC Isolation: Input to output HIPOT strength of 1500VAC for 60 seconds protects connected equipment.
• FCC Part 68 Cavity: The cavity conforms to FCC rules Part 68 Subpart F for approved network interfaces.

Frequently Asked Questions (FAQ)

Q: What do the two LED colors on this RJ45 magnetic jack indicate?

A: The J11VH5153NPF1 provides one green LED and one green yellow LED per port. In a typical design the green LED shows a valid 10/100Base-T link while the green yellow LED signals traffic activity, and both are driven from the magnetics side. Exact polarity and sourcing follow the schematic on the product drawing, so check the pinout before wiring the status circuits.

Q: Does this 100Base-T RJ45 jack need external magnetics?

A: No. The transformer, common mode choke and filter network are integrated inside the connector, so no external magnetics are required. The measured OCL is 350uH minimum at 100 kHz with 8 mA DC bias, insertion loss stays within 1.0 dB up to 100 MHz, and the input to output isolation is 1500VAC for 60 seconds. Simply connect the four data pairs to the host side.

Q: Is the jack compatible with standard shielded patch cords?

A: Yes. The 8P8C cavity accepts standard RJ45 plugs, and the 0.20 mm nickel plated metal shield grounds to the PCB through dedicated shield pins for EMI control. The cavity conforms to FCC Part 68 Subpart F mechanical requirements, and the recommended plug dimension on the drawing helps you verify mating compatibility with common shielded patch cords.
