Vertical Unshielded RJ45 Connector for PCB Applications JV112101UPC7（Cross Molex 85506-5001）

Product Overview

The JV112101UPC7 is a vertical unshielded RJ45 Connector for single port Ethernet interfaces. The receptacle is an 8P8C jack without magnetics, mounted perpendicular to the PCB in through-hole format. Contacts are full gold plated, and the spring wires are formed from 0.45 mm copper alloy wire with optional gold plating over nickel. The thermoplastic housing is rated UL94V-0. Electrical characteristics include 500 MOhm minimum insulation resistance, 30 mOhm maximum contact resistance, a 1000 VAC one minute withstanding voltage and a 1.5A current rating. The recommended PCB thickness is 1.60 plus or minus 0.05 mm.

Product Specifications

Product Features

• 1.5A Current Rating
  Supports powered Ethernet and auxiliary signal lines with margin over typical port loads.
• 30 mOhm Maximum Contact Resistance
  Full gold plated contacts hold the mating interface at low resistance across service life.
• 500 MOhm Minimum Insulation Resistance
  Ensures isolation between adjacent pins in dense single port layouts.
• 1000 VAC One Minute Withstanding Voltage
  Dielectric strength protects the port during surge and insulation testing.
• Full Gold Plated Contact Area
  Resists corrosion and keeps connection quality stable over repeated mating cycles.
• 0.45 mm Copper Alloy Spring Wire
  Provides consistent normal force for reliable 8P8C contact.
• UL94V-0 Thermoplastic Housing
  Flame retardant body suitable for consumer and industrial equipment.
• Vertical Through Hole Mounting
  Mounts perpendicular to the PCB for edge and rear panel Ethernet ports.

Frequently Asked Questions (FAQ)

Q: What is a vertical unshielded RJ45 connector used for?

A: A vertical unshielded RJ45 connector such as the JV112101UPC7 mounts perpendicular to the PCB and brings a single 8P8C Ethernet port to the edge or rear of an enclosure. Because the jack is passive and unshielded, it suits equipment where the transformer sits on the board or inside the PHY, and where the metal chassis or cable shield is handled elsewhere in the design.

Q: What are the benefits of the full gold plated contacts on this jack?

A: Full gold plating on the contact area keeps contact resistance at 30 mOhm maximum and protects the mating surface against corrosion across repeated patch cord insertions. Combined with 500 MOhm insulation resistance and a 1000 VAC one minute withstanding voltage, the jack maintains a stable connection over the service life of the equipment.

Q: What method is used to mount the JV112101UPC7 on the PCB?

A: The jack is designed for vertical through hole soldering. The drawing recommends a PCB thickness of 1.60 plus or minus 0.05 mm and provides a suggested PCB layout with pad positions for all pins, so the jack can be processed on standard wave soldering or hand soldering lines.
