5G Base-T Lan Transformer

Shop LINK-PP 5G Base-T Quad LAN transformers—discrete multi-gig Ethernet magnetics that isolate four copper PHY channels at five Gigabit in one package. This leaf lists quad-port SMD magnetics for multi-port switch and NIC boards that keep the RJ45 jack separate from the transformer. Return to the LAN Transformer hub, open the parent Quad Port LAN Transformer leaf, or compare sibling 2.5G Base-T Quad and 10G Base-T Quad. Confirm turns ratio, PoE class, CMC, isolation voltage, and ICM pinout on each product page before you place an order.

Frequently asked questions

01.What is a 5G Base-T quad-port LAN transformer on this page?
This leaf lists LINK-PP discrete Ethernet magnetics modules rated for 5G Base-T quad channels—quad-port packages that keep the RJ45 jack separate from the transformer. Return to the LAN Transformer hub or the parent Quad Port LAN Transformer leaf for related speeds.
02.How do I choose 5G Base-T Quad magnetics vs other Quad speeds?
Select 5G Base-T quad-port magnetics when your PHY targets 5 Gigabit on copper. For 2.5G quad-port see 2.5G Base-T Quad; for 10G quad-port see 10G Base-T Quad. Confirm turns ratio and PoE class on the datasheet.
03.Can these LAN transformers support PoE / PoE+ / PoE++?
Many LINK-PP magnetics modules are specified for PoE, PoE+, or higher power classes; support varies by SKU. Check the product page for PoE current rating, isolation voltage, and recommended center-tap wiring before you finalize the power budget.
04.Are LINK-PP LAN transformers Compatible with Pulse, Halo, Bothhand, or Würth PNs?
Yes—many listings map common OEM magnetics PNs (Pulse, Halo, Bothhand, Würth, and others) to the equivalent LINK-PP P/N. Open the Compatible product page for your OEM PN, compare pinout and electricals, then order the LINK-PP part. Contact support if your PN is missing.
05.Integrated RJ45 or discrete LAN transformer—which should I pick?
Use discrete magnetics from this leaf when the jack and transformer are separate on the PCB. Prefer a one-piece Integrated RJ45 when you want magnetics, LEDs, and shielding in a single magjack. Mechanical height, EMI, and BOM preference usually decide.
