Dual Port Shielded RJ45 Jack Connector JU124101DNC7（Cross TE 6116522-1/2、Cross Molex 44248-0085、Cross Amphenol RJHSE-J380-02）

Product Overview

The JU124101DNC7 is a shielded RJ45 receptacle arranged as a 1x2 dual port block for horizontal through-hole mounting. C5210-EH phosphor bronze terminals with gold flash plated contact areas and tin plated solder areas hold contact resistance at 50 mOhm maximum, while 500 MOhm insulation resistance and a 1000VAC one minute withstanding voltage protect both ports. The PA6T black housing withstands IR reflow at 260 Degree C for up to 10 seconds, the SUS304 shell is plated with nickel for EMI shielding, and the drawing recommends a PCB thickness of 1.60 plus or minus 0.05 mm.

Product Specifications

Product Features

• Two Ports in a 1x2 Block: The side by side layout provides two 8P8C interfaces within a 32.25 mm body, saving board area in dual line equipment.
• 1.5A High Current Contacts: C5210-EH phosphor bronze terminals carry 1.5A with 500 MOhm insulation resistance and 1000VAC dielectric strength across both ports.
• Gold Flash Plated Contacts: Contact areas are gold flash plated and solder areas are tin plated, keeping connection quality stable over repeated patch cord mating cycles.
• Nickel Plated SUS304 Shell: The SUS304-1/2H shell is plated with nickel and grounds through the PCB to suppress EMI between the two densely spaced ports.
• Reflow Soldering Ready: The PA6T black housing withstands IR reflow at 260 Degree C for up to 10 seconds, supporting standard SMT compatible assembly flows.

Packing Details

Each JU124101DNC7 is inspected, packed in anti-static bags and sealed in labeled inner boxes before shipment. Standard export cartons with internal cushioning protect the shield and through-hole pins during transport. Bulk, tray or tube packing can be arranged to suit manual assembly or automatic insertion equipment.

• VoIP Equipment: Two line 8P8C interface for IP phones and access devices.

Frequently Asked Questions (FAQ)

Q: Does this dual port RJ45 jack include magnetics?

A: No. The JU124101DNC7 is a passive shielded jack without a transformer, so it must be paired with external magnetics or a PHY that integrates them. Keeping the magnetics off the connector gives designers freedom to place the transformer for optimum layout across both ports, and the jack still provides 1000VAC dielectric strength and a grounded SUS304 shell for EMI control.

Q: How much current can the terminals of this jack carry?

A: The C5210-EH phosphor bronze terminals are rated at 1.5A with contact resistance of 50 mOhm maximum. Insulation resistance of 500 MOhm minimum plus a 1000VAC one minute withstanding voltage ensure the rating holds up in continuous service on powered Ethernet or auxiliary signal lines across both ports.

Q: Which soldering process does this shielded jack support?

A: The jack is designed for horizontal through-hole mounting and its PA6T housing withstands IR reflow at 260 Degree C maximum for 10 seconds, while the drawing recommends a PCB thickness of 1.60 plus or minus 0.05 mm. Gold flash plated contact areas and tin plated solder areas protect the terminals through the process, and the recommended PCB layout page shows pad positions for all pins including the shield tabs.
