Single Port Lan Transformer

Single Port Lan Transformer

Shop LINK-PP single-port LAN transformers (discrete Ethernet magnetics) for one-channel PHY isolation from 10/100 through Gigabit Base-T. This leaf focuses on single-port SMD magnetics modules—24-pin and related packages, PoE-capable options—for designs that keep the RJ45 jack separate from the transformer. Return to the parent LAN Transformer hub for dual- and quad-port magnetics, or browse 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 single-port LAN transformer?
A single-port LAN transformer is a discrete Ethernet magnetics module for one PHY channel, used when the RJ45 jack and magnetics are separate components. LINK-PP single-port SMD magnetics typically cover 10/100/1000 Base-T in 24-pin packages. See the parent LAN Transformer hub for dual- and quad-port options.
02.When should I use a discrete LAN transformer vs an integrated RJ45?
Choose a discrete LAN transformer plus a non-magnetic jack when layout, height, or BOM strategy keeps magnetics off the connector. Choose an integrated RJ45 when you want a one-piece magjack with LEDs and EMI shielding at the board edge.
03.Which Ethernet speeds do these single-port magnetics support?
This leaf focuses on single-port SMD magnetics for 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, Bourns, WE, or Bel LAN transformer PNs available as Compatible parts?
Yes—many listings map OEM single-port magnetics PNs to LINK-PP equivalents such as LP5007NL. 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 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.
