Series overview
WHYT molded power inductor sizes and ratings
WHYT molded power inductors are shielded SMD power inductors for the output stage of DC-DC buck converters, from point-of-load rails to high-current stages. They are also listed as molded chokes, composite inductors or high current inductors. Footprints run from 7.0 × 6.6 mm (WHYT0630 series) to 23.5 × 22 mm (WHYT2313 series), with heights from 2.8 mm to 12.6 mm. For thinner bodies, see the WHYTA low profile inductors; for a smaller footprint, the WHYTP compact parts.
Heights within a footprint
On 11.5 × 10 mm, the WHYT1030, WHYT1040 and WHYT1050 series stand 2.8, 3.8 and 4.8 mm tall. On 13.45 × 12.6 mm, WHYT1250, WHYT1260 and WHYT1265 stand 4.8, 5.8 and 6.5 mm. Compare them at your exact inductance value.
IRMS and ISAT differ
The two current ratings do not track each other. The WHYT1030 series lists 4–50 A IRMS but 2.6–33 A ISAT, so saturation can bind first, while WHYT1250 lists 3–50 A IRMS and 5–75 A ISAT. Check both for your value.
Inductance and DCR
Low values start at 0.15 µH in the WHYT1040 series, and the WHYT1260 series reaches 150 µH. DCR spans 0.65–340 mΩ within WHYT1040 alone, so read the datasheet figure for your inductance, not the series range.
Applications
Where WHYT molded power inductors are used
Molded construction largely contains the magnetic field, so these parts can sit near sensitive circuits.
Switch and router board rails
Point-of-load bucks on switch and router boards often use mid-size parts such as the WHYT1050 series (11.5 × 10 × 4.8 mm) or WHYT1265 series (13.45 × 12.6 × 6.5 mm) to balance ripple, DCR and height under the airflow.
High-current DC-DC stages
Where one inductor carries tens of amps, a high current molded inductor such as the WHYT2313 series, 23.5 × 22 × 12.6 mm with 0.95–40 mΩ DCR, or the WHYT1770 series at 3.7–29 A IRMS keeps conduction loss down.
Secondary rails on dense boards
Memory, I/O and PHY supplies often fit the 7.0 × 6.6 mm footprint. As a buck inductor there, the WHYT0630 series at 2.8 mm high lists 1.5–24 A IRMS and 2–34 A ISAT.

FAQ
WHYT molded power inductor questions
Supply, low-height choices within WHYT and the files available for layout.
What does the WHYT range cover?
Footprints from about 7 by 6.6 millimetres up to 23.5 by 22, with heights from under 3 millimetres to over 12. Inductance spans roughly 0.15 to 150 microhenries, DC resistance from about 0.65 milliohm on the largest low-value parts, and RMS current up to around 70 amps on the largest body.
How do the size codes work?
The four digits encode the footprint and height band, and the datasheet gives exact dimensions in millimetres. Within one footprint, a taller body has more winding volume, which generally means lower DC resistance and higher current at the same inductance. Read the dimensions rather than inferring from the code.
Which size should I start from?
Start from the height clearance over your converter, because that usually binds first. Then check which bands within that height offer your required inductance while meeting IRMS for steady-state current and ISAT for peaks. Narrow from mechanical constraint to electrical fit, not the other way round.
How much current can the largest parts carry?
The largest body in the range reaches about 70 amps RMS and 60 amps saturation, with DC resistance below one milliohm at the low inductance end. Those figures vary with the inductance value chosen, so read the specific part number rather than the series-level range.
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 height clearance, and a sales engineer will shortlist candidates.
Is VOOHU a WHYT molded power inductor manufacturer?
Yes. VOOHU manufactures WHYT molded power inductors in its own magnetics factory in Mianyang, China, from the 7.0 × 6.6 mm WHYT0630 series to the 23.5 × 22 mm WHYT2313 series. The same factory makes the WHYTA and WHYTP ranges.
Which WHYT series fit under a 3 mm height limit?
The WHYT1030 series (11.5 × 10 × 2.8 mm, 0.22–33 µH, 4–50 A IRMS) and the WHYT0630 series (7.0 × 6.6 × 2.8 mm, 0.22–47 µH, 1.5–24 A IRMS) do. Below that height, compare the WHYTA low profile range.
Are 3D models or PCB footprints available for WHYT molded power inductors?
Not as downloads. The selector lists a datasheet for each WHYT series, so build the land pattern from the datasheet drawing and confirm the height against your enclosure. Our FAE team can review the footprint with you before release.
