Key Features
- Single-port 1×1 Gigabit Ethernet RJ45 connector supporting 10/100/1000BASE-T on a single device
- Integrated magnetics meeting IEEE 802.3 isolation and common-mode rejection requirements up to 1500 V
- Low-profile housing enabling front-panel or PCB-edge mounting in height-constrained network appliances
- Built-in LED indicators for link and activity status on Gigabit ports without external driver circuitry
- Through-hole termination with tab-lock retention for robust PCB mounting in vibration environments
Applications
The J0G-0009NL is designed for embedded Gigabit Ethernet ports in single-board computers, industrial network switches, IP cameras, and VoIP gateways where a low-profile RJ45 connector with onboard magnetics simplifies BOM and reduces PCB area. Its integrated 1500 V isolation and built-in LED indicators make it directly compatible with popular Ethernet PHYs such as the Marvell 88E1111 and Microchip LAN8720, eliminating the need for discrete transformer modules. Network equipment manufacturers also specify it in 1U rackmount appliances and ruggedised industrial controllers requiring IEEE 802.3 compliant Gigabit connectivity at port densities of 1 to 8 ports per board.

Frequently Asked Questions
What Ethernet standards does the J0G-0009NL support, and can it handle Gigabit speeds on existing Cat5e cabling?
The J0G-0009NL supports 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet standards. At Gigabit speed over 1000BASE-T it uses all 4 pairs of Cat5e or Cat6 cable simultaneously, achieving 1 Gbps full-duplex over runs up to 100 metres. The integrated magnetics meet the IEEE 802.3 return loss and insertion loss masks required for error-free 1 Gbps operation at that distance.
Does J0G-0009NL include integrated magnetics, and what isolation voltage does that provide?
Yes, the J0G-0009NL incorporates integrated isolation transformers that provide 1500 V RMS dielectric withstand voltage between the cable side and the PHY side, meeting IEEE 802.3 clause 40.8 requirements. This eliminates the need for a separate discrete Ethernet transformer module, reducing BOM count by one component and freeing up roughly 100 mm² of PCB area per port in compact gateway and router designs.
Which Ethernet PHY chips are directly compatible with J0G-0009NL for a 1 Gbps embedded design?
The J0G-0009NL's integrated magnetics and centre-tap architecture are compatible with popular RGMII and MII Gigabit PHYs including the Marvell 88E1111, Microchip KSZ9031, Realtek RTL8211, and Intel I210. Designers connect the PHY's MDI pins directly to the connector's centre-tap outputs, following Pulse's application schematic for 1500 V isolated, 1 Gbps designs without any external transformer or common-mode choke.
How does the low-profile design of J0G-0009NL benefit 1U rack appliances and IoT gateway enclosures?
The J0G-0009NL's low-profile single-port body stands shorter than standard RJ45 connectors, enabling PCB placement within the height constraints of 1U (44.45 mm) rackmount chassis and compact IoT enclosures less than 30 mm tall. By integrating magnetics into the same package as the 8P8C receptacle, board height is not further increased by a stacked discrete transformer, allowing the Gigabit port to fit within enclosures that could not accommodate conventional magnetic-plus-connector stacks.
