Product Specifications

Key Benefits of LINK-PP LPJG16443AENL / Halo HFJT1-E1G41-L12RL Compatible Magjack

• Full Gigabit 1000BASE-T Speed (IEEE 802.3ab): Embeds an 8-core transformer and common-mode choke matrix that isolates and filters 4 differential pairs, ensuring clean 1 Gbps eye diagrams with minimal differential insertion loss.
• Industrial Operating Temperature Range (-40°C to +85°C): Built with high-grade FR4 substrate and durable housing to withstand severe thermal fluctuations in unconditioned outdoor equipment and factory automation systems.
• Tab-UP Mechanical Latch & EMI Shield Spring Tabs: Tab-UP mechanical latch orientation aligns with standard front-panel enclosures, while EMI spring tabs on the metal shield frame press against chassis cutouts to suppress radiated emissions.
• Integrated Green/Yellow Visual Status LEDs: Built-in bi-color LED indicators provide clear visual diagnostics for Gigabit link establishment, port speed, and data activity status.
• Integrated Bob Smith Termination (BST) & Auto-MDIX: Built-in 75-ohm BST circuit routes common-mode EMI noise and ESD transients safely to ground, while Auto-MDIX logic supports automatic straight-through or crossover cable detection.
• Direct Second Sourcing for Halo Electronics HFJT1-E1G41-L12RL: Identical 10p8c through-hole PCB land pattern and pinout allow seamless drop-in secondary sourcing to reduce procurement lead times.

Integrated Magnetics & 1000BASE-T Signal Architecture

The LINK-PP LPJG16443AENL utilizes an advanced Gigabit Integrated Connector Module (ICM) architecture that embeds 1000BASE-T magnetics directly behind the 10p8c contact pins, eliminating high-frequency noise radiation caused by long trace runs on the motherboard.

8-Core Gigabit Transformer & Choke Configuration

Featuring a 1CT:1CT transmit and receive turns ratio with 8 magnetic cores per port, the LPJG16443AENL establishes 1500Vrms galvanic isolation between the Ethernet PHY transceiver chip and the external network cable. The 8-core layout provides precise impedance matching across transmit and receive differential pairs, suppressing inter-channel crosstalk and common-mode noise.

Bob Smith Termination (BST) & ESD Rejection

The integrated Bob Smith Termination (BST) network utilizes high-voltage capacitors and precision resistors to balance line impedance on unused cable pairs. This prevents common-mode noise reflection, reduces radiated EMI emissions, and enhances system ESD immunity during cable plugging.

PCB Mounting & Mechanical Specifications

Designed for automated Through-Hole Technology (THT) assembly, the LPJG16443AENL incorporates robust mechanical features to ensure structural integrity on FR4 substrates.

Tab-UP Latch Geometry & EMI Shield Tabs

With package dimensions of 13.50mm H x 21.25mm L x 15.95mm W, the LPJG16443AENL provides a compact footprint. Integrated Green/Yellow LEDs provide clear visual link status and data activity diagnostics, while T-Post mechanical pegs anchor the housing firmly to the motherboard during cable plugging.

Target Applications: Industrial PCs, Fieldbus Systems, and Digital Cameras

Combining IEEE 802.3ab Gigabit speed, industrial thermal endurance (-40°C to +85°C), BST noise suppression, and Halo HFJT1-E1G41-L12RL compatibility, the LINK-PP LPJG16443AENL supports diverse embedded systems:

• Industrial PCs & Fieldbus Automation Gateways: Ideal for DIN-rail industrial computers, Modbus/PROFINET fieldbus gateways, and programmable logic controllers (PLCs).
• Machine Vision Digital Cameras & Surveillance Systems: Deployed in industrial machine vision cameras, smart inspection cameras, and outdoor video gateways.
• Commercial Routers & Industrial Network Switches: Suitable for commercial security firewalls, industrial Wi-Fi routers, and automation controllers.

How to Select and Verify LPJG16443AENL vs. Halo HFJT1-E1G41-L12RL

Hardware design engineers and procurement specialists evaluating the LINK-PP LPJG16443AENL as a second-source replacement for Halo Electronics HFJT1-E1G41-L12RL should verify the following core parameters:

• 8-Core Gigabit Magnetics Compatibility: Confirm that an 8-core magnetic matrix (4 differential pairs) and a 1CT:1CT turns ratio match your Gigabit Fast Ethernet PHY transceiver reference design.
• Operating Temperature Envelope: Confirm that the -40°C to +85°C industrial temperature rating satisfies your product's environmental specification.
• Mechanical Latch & Footprint Alignment: Verify that the Tab-UP latch direction, 10p8c through-hole pin arrangement, and T-Post peg locations match the HFJT1-E1G41-L12RL PCB land pattern.
• Package Height & EMI Tab Clearance: Ensure that the 13.50mm package height and external EMI spring tabs fit within your front-panel bezel window.
