Dual Port Lan Transformer

Shop LINK-PP dual-port LAN transformers (discrete Ethernet magnetics) for two-channel PHY isolation from 10/100 through Gigabit Base-T. This leaf focuses on dual-port SMD magnetics modules—often 50-pin packages—for designs that keep the RJ45 jack separate from the transformer. Return to the parent LAN Transformer hub for single- and quad-port options, or open Integrated RJ45 when you prefer a one-piece magnetic jack. Match turns ratio, PoE class, pin count, and reel packaging on each product page before ordering.

Frequently asked questions

01.What is a dual-port LAN transformer?
A dual-port LAN transformer is a discrete Ethernet magnetics module for two PHY channels, used when RJ45 jacks and magnetics are separate components. LINK-PP dual-port SMD magnetics typically cover 10/100/1000 Base-T in 50-pin packages. See the parent LAN Transformer hub for single- and quad-port options.
02.When should I use a discrete dual-port LAN transformer vs integrated RJ45?
Choose discrete dual-port magnetics plus non-magnetic jacks when layout, height, or BOM strategy keeps magnetics off the connector. Choose an integrated RJ45 when you want a one-piece magjack with LEDs at the board edge.
03.Which Ethernet speeds do these dual-port magnetics support?
This leaf focuses on dual-port SMD magnetics for 10/100 and 10/100/1000 Base-T where stocked. Confirm turns ratio, PoE capability, and ICM pinout against your PHY reference design before ordering.
04.Are Pulse, Halo, WE, or Bothhand dual-port LAN transformer PNs available as Compatible parts?
Yes—many listings map OEM dual-port magnetics PNs to LINK-PP equivalents such as LP5020NLR. Open the Compatible product page, confirm pinout and electrical specs, then order the LINK-PP P/N shown.
05.What should I check before ordering a dual-port LAN transformer?
Match pin count, turns ratio, PoE class, operating temperature, and reel/tape packaging to your BOM and PHY datasheet. Recommended land patterns and electrical tables are on each product page.
