Series overview
Using the 4532E chip LAN transformer
The 4532E chip LAN transformer is a non-PoE X’fmr+CMC part for 100/1000BASE-T ports, placed between the PHY and the RJ45 jack. It also goes by non-PoE LAN transformer or SMD LAN transformer, and the family is built around WHLT-4532E-201MGN. For PoE, see the 4532B PoE chip LAN transformers; for multi-gig ports, the 3532A range.
OCL at 8 mA bias
Its OCL is listed as 200 µH at an 8 mA DC bias. Compare it with other parts only under the same bias and test condition.
Assembly checks
The SMD body suits pick-and-place and reflow. Keep the pairs short and symmetrical between PHY and transformer, and re-measure OCL on the first reflowed boards.
When to switch size
For gigabit PoE af or PoE at, move to the 4532B range; for 2.5G/5G or 10GBASE-T, to 3532A, 4532B or 5335A; for PoE bt, to 5335A.
Applications
Where a 4532E chip LAN transformer fits
Any copper gigabit port without PoE is a candidate.
Routers and gateways
Home and small-office routers, gateways and set-top boxes can use WHLT-4532E-201MGN on 100/1000BASE-T LAN or WAN ports with no PoE.
NAS units and mini PCs
Storage boxes, mini PCs and single-board computers with a gigabit RJ45 port can place this chip Ethernet transformer close to the PHY.
Controllers and terminals
Embedded controllers, HMIs and kiosk terminals powered from their own supply can use this non-PoE chip LAN transformer on their Ethernet port.

FAQ & related guides
4532E chip LAN transformer questions
Answers on manufacturing, link speeds and the design files for WHLT-4532E-201MGN.
Is WHLT-4532E-201MGN a common mode choke?
Its datasheet identifies a Pulse Transformer, used here as a LAN signal transformer. Do not rely on a legacy page title that calls it a common mode choke; confirm its function from the part documentation and schematic.
Can 4532E be used as a PoE port option?
The current WHLT-4532E-201MGN datasheet explicitly lists Non-PoE. This draft does not recommend it as a PoE part. Share the power requirements to review candidates with applicable PoE documentation.
What does 200 µH at 8 mA mean?
It is the OCL condition under the specified DC bias, not a PoE current rating. Also retain the 100 kHz, 0.1 V and minimum-value conditions when comparing it—not just the 200 µH number.
Can 4532E and 4532B be swapped without changing the PCB?
The family names do not establish that. Compare the full parts’ dimensions, pads, winding pins and power conditions. Send the existing part and board drawing so FAE can review candidates and any required changes.
Can I request samples directly for the current part in this family?
Yes. Send WHLT-4532E-201MGN, the quantity and requested timing. If the project has not yet settled its PoE or speed requirements, share those first for engineering selection support.
Who manufactures the 4532E chip LAN transformer?
VOOHU manufactures it in its own magnetics factory in Mianyang, China, alongside the 3532A, 4532B and 5335A sizes, which helps if a later revision needs PoE or a higher rate.
Does the 4532E work on a port that links at 100 Mbps?
Yes. WHLT-4532E-201MGN is listed for 100/1000BASE-T, so it is intended for ports that link at 100 Mbps or at gigabit. Follow your PHY reference circuit for the center tap and termination.
Which design files are published for WHLT-4532E-201MGN?
A datasheet, a 3D model and a PCB footprint. Use the footprint for pads and pin 1, the 3D model for clearance around the RJ45 jack, and the datasheet for the schematic and electrical limits.
