Key Benefits of LINK-PP LP83601NL Dual-Port Discrete LAN Transformer

• Discrete Magnetics Architecture Provides PCB Design Flexibility: Placing discrete transformers directly on the motherboard allows hardware engineers to optimize PHY-to-connector trace routing, implement custom surge protection networks, or use specialized non-magnetic RJ45 connectors.
• Dual-Port High-Density Integration (36 Pins): Integrates magnetics for two full 1000BASE-T Gigabit channels inside a compact 32.70mm x 8.5mm footprint, reducing component count and board layout complexity.
• T,C,S Circuit Configuration for Superior Signal Integrity: Combines isolation transformers (T), common-mode chokes (C), and shunt autotransformers (S) across all 4 differential pairs per port, minimizing insertion loss and suppressing high-frequency EMI radiation.
• 1500Vrms Galvanic Isolation Voltage: Protects sensitive Ethernet PHY transceiver chips from cable discharge events (CDE), ESD transients, and high-voltage common-mode ground loops.
• Tape & Reel Packaging for Automated Assembly: Supplied in industry-standard Tape & Reel format for automated Pick & Place machinery, ensuring high manufacturing yields and low production costs.
• Industry-Standard Pinout Second Sourcing: Identical 36-pin through-hole/surface-mount footprint allows seamless drop-in secondary sourcing for standard 36-pin dual-port Gigabit LAN magnetics.

Discrete LAN Magnetics & T,C,S Signal Isolation Architecture

In high-performance networking equipment, hardware architects frequently specify discrete LAN magnetics modules like the LINK-PP LP83601NL rather than Integrated Connector Modules (Magjacks) to meet strict EMI, layout, or multi-channel PHY requirements.

16-Core Dual-Channel Magnetics & T,C,S Topology

Featuring 16 magnetic cores (8 cores per port) configured in a 1CT:1CT turns ratio, the LP83601NL isolates two independent 1000BASE-T Ethernet PHY channels. Each channel contains four transmit and receive lines equipped with isolation transformers, common-mode chokes, and shunt autotransformers (T,C,S topology). This complex magnetic arrangement maintains high return loss (>12 dB at 80 MHz) and low insertion loss (<1.0 dB up to 100 MHz), guaranteeing clean Gigabit Ethernet eye diagrams.

36-Pin Open Frame Package & Thermal Performance

The 36-pin open-frame construction provides a low package height of 12.0mm [.472 in] while allowing natural air convection around the toroidal ferrite cores. This open-frame geometry prevents thermal buildup during continuous high-throughput data transfers, maintaining stable inductance and signal integrity across the 0°C to +70°C commercial operating temperature range.

PCB Mounting & Mechanical Specifications

Engineered for automated high-volume production lines, the LP83601NL combines robust mechanical construction with precise electrical pin alignment.

36-Pin Package Footprint & Automation Assembly

With package dimensions of 12.0mm H x 32.70mm L x 8.5mm W, the 36-pin layout provides precise pin pitch for through-hole or surface-mount soldering on FR4 PCBs. Supplied in Tape & Reel packaging, the LP83601NL feeds seamlessly into automated placement machines, minimizing manual handling and solder bridging defects.

Target Applications: Dual-Port NICs, Enterprise Switches, and Embedded Systems

Combining IEEE 802.3ab Gigabit compliance, 36-pin dual-port density, T,C,S noise suppression, and open-frame thermal performance, the LINK-PP LP83601NL supports diverse networking platforms:

• Dual-Port PCIe Gigabit Network Interface Cards (NICs): Ideal for dual-port server adapters, network acceleration cards, and FPGA-based offload engines requiring discrete PHY magnetics.
• Multi-Port Enterprise Switches & Core Routers: Deployed on high-density motherboard switch fabrics, enterprise edge routers, and security gateways.
• Industrial PCs & Embedded Mainboards: Suitable for dual-LAN industrial computers, single-board computers (SBCs), and smart grid communication controllers.

How to Select and Verify LINK-PP LP83601NL LAN Transformer

Hardware design engineers and procurement specialists evaluating the LINK-PP LP83601NL for new designs or secondary-source qualification should verify the following core parameters:

• 36-Pin Footprint & Pinout Alignment: Confirm that the 36-pin land pattern, row spacing, and overall package dimensions (32.70mm L x 8.5mm W) match your motherboard Gerber layout.
• PHY Transceiver Reference Design Matching: Verify that a 1:1 primary-to-secondary turns ratio and T,C,S magnetic configuration align with your Gigabit PHY transceiver chip recommendation (IEEE 802.3ab).
• Dual-Port Channel Allocation: Ensure that your schematic routes two independent 4-pair 1000BASE-T Ethernet PHY channels through the 36-pin module pins correctly.
• Assembly Packaging Format: Confirm that Tape & Reel packaging matches your contract manufacturer's automated SMT/THT Pick & Place reel feeder specifications.
