Tab-Up 1000BASE-T RJ45 Magnetic Jack for Gigabit Ethernet Applications J11GG116DPT1F1（Cross WÜRTH ELEKTRONIK 7499111121A）

Product Overview

The J11GG116DPT1F1 is a single port 1x1 magnetic RJ45 Connector with an integrated 1000BASE-T filter, built in tab-up orientation for through-hole assembly. The product uses a high-temperature black PBT housing rated UL94V-0 and a 0.20 mm shield with 30 uinch minimum nickel plating. Its 0.35 mm phosphor bronze terminals carry a 50 uinch nickel underplate, 80 uinch minimum tin on the termination end and 30 uinch minimum gold on the contact area. Electrical characteristics include a 1 CT to 1 CT turns ratio within 3 percent, 350 uH minimum OCL at 8 mA DC bias, 1.2 Ohms maximum DCR, 1500 VAC input-to-output isolation for 60 seconds and insertion loss of -0.85 dB maximum up to 100 MHz. LED 1 is yellow and LED 2 is green.

Product Specifications

Product Features

• 1000BASE-T Integrated Filter
  The transformer is built into the tab-up housing, so the PHY connects directly to the RJ45 Connector without external magnetics.
• 1 CT : 1 CT Turns Ratio within 3 Percent
  Keeps channel matching consistent for Gigabit signal integrity across production units.
• 350 uH Minimum OCL with 8 mA DC Bias
  Open circuit inductance holds the transmission characteristic stable under bias.
• 1.2 Ohms Maximum DCR
  Low winding resistance limits power loss in the transmit path.
• 1500 VAC Input to Output Isolation for 60 Seconds
  Protects electronics from ground potential differences between cable plant and board.
• 30 uinch Gold Plated Contact Area
  Gold over the 50 uinch nickel underplate keeps the mating interface stable and low resistance.
• 50 uinch Nickel Underplate with 80 uinch Tin Termination
  Nickel diffusion barrier on all areas with reliable tin solder joints on the PCB.
• LED 1 Yellow and LED 2 Green Status Indicators
  Provides link and activity indication directly at the port face.
• Tab-Up Through Hole Mounting
  Latch on the upper side of the port for standard through-hole assembly.

Frequently Asked Questions (FAQ)

Q: What is a tab-up 1000BASE-T RJ45 magnetic jack used for?

A: A tab-up 1000BASE-T RJ45 magnetic jack such as the J11GG116DPT1F1 provides a single 10P8C Ethernet port with the transformer built into the housing, so the PHY connects directly to the RJ45 Connector without external magnetics. The tab-up orientation positions the latch on the upper side of the port, and the yellow and green LEDs provide link and activity indication at the port face.

Q: What are the benefits of the integrated 1000BASE-T filter?

A: The integrated filter provides a 1 CT to 1 CT turns ratio within 3 percent, 350 uH minimum open circuit inductance with 8 mA DC bias, 1.2 Ohms maximum DCR and insertion loss no worse than -0.85 dB up to 100 MHz. This removes external magnetics from the bill of materials, shortens PHY routing and guarantees consistent Gigabit signal integrity across production units.

Q: What mounting method does the J11GG116DPT1F1 use?

A: The jack is designed for tab-up through hole assembly on a standard PCB. The drawing provides a suggested PCB layout with pad positions for all signal pins, LED pins and the shield, and the 0.35 mm phosphor bronze terminals with 80 uinch minimum tin on the termination end solder reliably on standard through-hole lines.
