How to select
A practical selection sequence
Narrow the published fields in sequence, compare the remaining candidates and verify the part-specific files before design-in.
- 01
Identify the component function
Distinguish a transformer, a common mode choke and a complete coupling network. The CHIP LAN label alone is not a selection criterion.
- 02
Check the data rate, PHY and power architecture
Record the PHY model, port count, target data rate and PoE or non-PoE requirement. One chip-format component is not necessarily a complete set of port magnetics.
- 03
Compare parameters with their test conditions
Compare OCL together with test frequency, voltage and DC bias. Compare common mode impedance at the stated frequency. Common mode impedance is not the Ethernet differential impedance, and OCL bias current is not a PoE current rating.
- 04
Complete layout review and sample validation
Check pin assignments, winding connections, recommended land pattern, isolation paths and reflow requirements for the exact part, then validate signal and EMC performance in the target circuit.

Technical performance & application fit
Validate the complete design context
Application suitability is part-number specific. Treat the catalog fields as a shortlist, then confirm the design against the linked technical files.
Switches and industrial gateways
- Start with the PHY, speed and power architecture of each port. Review the required component count, isolation requirements and board space; do not treat one chip component as a complete multiport module.
IP cameras, wireless access points and access-control devices
- Review both the Ethernet signal path and the equipment power architecture. Power conversion after PoE extraction is a separate function: a CHIP LAN signal transformer is not a substitute for a PoE power transformer.

Category overview
Chip LAN transformers and companion chokes
Surface mount magnetics for Ethernet come in two related forms, and knowing which one a part number is saves a lot of confusion.

Transformer or choke
A chip LAN transformer provides the isolation and signal coupling the Ethernet port needs. A companion common mode choke is a separate part that improves common mode rejection alongside it. Some designs use both. Read what the part actually is first, because the two are specified differently.
Package size is a first filter only
Codes such as 2012, 3216 and 4532 describe the footprint, and they make a useful first cut when board area is constrained. They say nothing about speed rating, PoE capability or insertion loss. Two parts in the same package can be specified for very different links, so always read the electrical data.
Speed and PoE still govern
As with any Ethernet magnetics, the link speed sets the signal integrity requirement and the PoE class sets the bias current the part has to tolerate. A compact package does not relax either constraint. Filter on speed and PoE first, then use package size to narrow what remains.
FAQ & related guides
Questions before design-in
These answers guide the page workflow. Part-specific engineering limits still come from the linked technical files.
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.
Engineer support
