Shielded RJ45 Modular Jack Through Hole Connector JD114107UNC7（Cross Molex 44661-0002 ）

Product Overview

The JD114107UNC7 is a shielded RJ45 modular jack supplied in an 8P8C Cat5e configuration. Phosphor bronze contacts with Au/Sn plating hold contact resistance at 20 mOhm maximum, while 500 MOhm insulation resistance and a 1000VAC dielectric test protect signal integrity. The PA6T UL94V-0 housing and metal shell operate from -40 to +85 Degree C, covering industrial as well as consumer environments.

Product Specifications

Product Features

• 1.5A High Current Contacts: Each of the eight phosphor bronze contacts is rated at 1.5A, above the level of typical LAN jacks.
• Full Metal Shielding: The one piece metal shell grounds through shield tabs to suppress EMI in dense boards.
• Au/Sn Plated Contacts: Au/Sn plating over phosphor bronze keeps contact resistance at 20 mOhm maximum initial.
• UL94V-0 Housing: PA6T insert molded and housing parts meet UL94V-0 flame retardancy in black finish.
• Wide Temperature Range: Operating and storage ratings of -40 to +85 Degree C support demanding deployments.

Packing Details

Each JD114107UNC7 is inspected, packed in anti-static bags and sealed in labeled inner boxes before shipment. Standard export cartons with internal cushioning protect the 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.

Applications

• Motherboards: Standard 8P8C LAN port for desktop and embedded boards.
• Set-Top Boxes: Shielded Ethernet access for home entertainment terminals.
• DSL Modems: Cost effective Cat5e interface for customer premises equipment.
• Embedded Control Boards: Passive RJ45 Connector port for industrial controllers.
• Game Consoles: Durable high current port for networked entertainment devices.

Frequently Asked Questions (FAQ)

Q: Does this RJ45 modular jack include magnetics?

A: No. The JD114107UNC7 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, and the jack still provides 1000VAC dielectric strength and a grounded metal shield for EMI control.

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

A: Every one of the eight phosphor bronze contacts is rated at 1.5A with a voltage rating of 150VAC RMS. The Au/Sn plating keeps initial contact resistance at 20 mOhm maximum, and insulation resistance of 500 MOhm minimum plus a 1000VAC one minute dielectric test ensure the rating holds up in continuous service on powered Ethernet or auxiliary signal lines.

Q: Which patch cords work with this Cat5e modular jack?

A: The 8P8C cavity accepts standard RJ45 plugs used on Cat5e and lower category patch cords. Contact spacing and cavity geometry follow the modular jack dimensions on the drawing, and the recommended PCB layout page shows pad positions for the through-hole pins. For shielded cords, the metal shell terminates shield ground through the dedicated tab on the PCB footprint.
