One body, one footprint
Every value in the WHYTP0320 series shares the 3.4 × 3.2 × 1.8 mm body, so one land pattern covers the 0.33–10 µH span while you tune the converter.

WHYTP Compact Molded Inductors
WHYTP uses the smallest footprint in the range at 3.4 by 3.2 by 1.8 millimetres, covering 0.33 to 10 microhenries with RMS currents to 8 amps. It suits point-of-load rails and modules where board area rather than height is the limit.

Series overview
WHYTP compact molded power inductor selection
The WHYTP compact molded power inductor is a 3.4 × 3.2 × 1.8 mm shielded SMD power inductor for small DC-DC rails. It is also searched as a small molded power inductor or compact molded inductor. The WHYTP0320 series covers 0.33–10 µH. For more current, compare the WHYTA low profile parts or the WHYT range.
Current by value
IRMS runs 1.4–8 A and ISAT 1.6–10 A across the WHYTP0320 series, with the higher currents at low values. Check the datasheet for your value.
Resistance budget
DCR spans 21–422 mΩ in the WHYTP0320 series. Toward the high-inductance end, conduction loss climbs quickly with load, so check I²R loss against your efficiency target.
Height and area
At 1.8 mm, WHYTP0320 matches the height of the WHYTA0420 series on the WHYTA page, in a smaller footprint; WHYTA0412 there is thinner, at 1.0 mm.
Applications
Where WHYTP molded power inductors are used
Board area, not height, is the usual limit here.
Local bucks for I/O and memory
I/O, memory and PHY supplies often need only a few amps. The WHYTP0320 series, at 1.4–8 A IRMS, fits right beside the load.
Compute modules and compact boards
Compute modules, camera boards and sensor hubs carry several small regulators. A 3.4 × 3.2 mm molded inductor per rail keeps the power section compact.
Battery-powered handheld instruments
Handheld and battery-powered devices run small bucks where every square millimetre counts. Check DCR at your load current, since it sets conduction loss and runtime.

Samples and quotes
Samples are available for evaluation, and selected parts are free of charge. Our FAE team will be glad to confirm the options for your project. For a quote, give the inductance value and quantity; typical lead time is 7–10 days.
Replacement candidates
Send the part number and datasheet of your current small molded inductor. Our FAE team compares footprint, inductance, DCR, IRMS and ISAT, then suggests WHYTP0320 values to validate with samples before production.
Quality
VOOHU is ISO 9001 and ISO 14001 certified. Since 2018 VOOHU has supplied more than 1,500 customers, including 150+ listed companies. WHYTP parts are built in the Mianyang factory.
FAQ
WHYTP compact molded power inductor questions
Supply, choosing a value and layout files.
How small is WHYTP?
The body is 3.4 by 3.2 millimetres with a height of 1.8 millimetres, the smallest footprint in the molded range. Inductance covers 0.33 to 10 microhenries, DC resistance runs from about 21 to 422 milliohms, RMS current to 8 amps and saturation to about 10 amps.
What is it suited to?
Point-of-load rails and compact modules where board area is the limiting factor rather than height. The current capability suits secondary rails and local regulation rather than main power stages. For higher current in a similar height, compare the larger footprints in the WHYTA range.
Why is the DC resistance higher than larger parts?
Less winding volume means thinner wire or fewer turns in a smaller window, and resistance rises accordingly. At 21 to 422 milliohms depending on inductance value, conduction loss matters more than on larger parts, so calculate it against your actual RMS current before committing.
When should I move to a larger footprint?
When the RMS current exceeds what 8 amps allows with margin, when the DC resistance loss is too high for the efficiency target, or when you need inductance above 10 microhenries. If board area is truly fixed, send the conditions to our engineers to assess alternatives.
How do I request samples or a quote?
With a complete part number, send the part number, quantity, delivery region and the date you need it. If you are still selecting, send the output current, switching frequency, ripple budget and the board area available, and a sales engineer will shortlist candidates.
Does VOOHU manufacture the WHYTP molded power inductor?
Yes. VOOHU manufactures the WHYTP0320 series in its own magnetics factory in Mianyang, China, alongside the WHYTA and WHYT ranges, so one supplier can cover every molded inductor size on a board.
How do I pick a WHYTP0320 inductance value?
Work out the inductance from your switching frequency and ripple target, then check that the value’s IRMS and ISAT cover the load with margin. Across the series, IRMS spans 1.4–8 A and ISAT 1.6–10 A.
Is a PCB footprint available for the WHYTP molded power inductor?
Not as a download. The selector lists a datasheet for the WHYTP0320 series only, so build the land pattern from its drawing; our FAE team can review it on request.
