Package size and dimensions
Stated as length by width by height in millimetres. Height is often the binding constraint, and within one footprint the taller option usually carries more current.

By series
Molded inductor series by size band
Series split by footprint and height, which together set current capability and loss.
選定方法
Selecting a molded power inductor in four steps
Ripple sets the inductance; IRMS and ISAT set the size; height often decides.
- 01
Calculate the inductance
Derive it from input and output voltage, switching frequency and the ripple current you can accept. Then check the tolerance band at its worst corner.
- 02
Check both current ratings
IRMS caps the continuous current by temperature rise. ISAT caps the peak by inductance roll-off. Your design has to satisfy both, not the friendlier one.
- 03
Pick the size band
Larger footprints and taller bodies give lower DC resistance and higher current. Work back from the height clearance over the converter.
- 04
Verify on the board
Measure ripple, efficiency and the inductor's temperature at full load in the real enclosure, then confirm at the highest rated ambient.
Parameters
Reading molded inductor ratings
IRMS and ISAT are defined differently and both have to be satisfied.
Inductance value
Ranges from about 0.1 to 150 microhenries across the family. Low values suit high switching frequency; higher values reduce ripple at lower frequency.
DC resistance
From about 0.65 milliohm on the largest low-value parts up to several hundred milliohms on the small high-inductance ones. It sets conduction loss.
IRMS
The continuous RMS current producing the datasheet's stated temperature rise. It is the steady-state limit and must be derated for high ambient temperature.
ISAT
The current at which inductance falls by the stated percentage. It caps the instantaneous peak, including startup inrush and load transients.
シールド
Molded construction encloses the winding in magnetic material, so the part is inherently shielded. That reduces coupling into nearby traces and lowers audible noise.
比較
Molded inductor series side by side
Footprint and height together decide what current and inductance are available.

用途別確認
Where molded power inductors are used
Confirm output current, switching frequency, ripple budget and height clearance.
DC-DC converters and POL rails
- Confirm the ripple budget and switching frequency, then check IRMS at the real ambient and ISAT against startup inrush.
Automotive and industrial supplies
- Ambient temperature and vibration both matter. Derate IRMS for the environment and confirm the mounting suits the vibration profile.
Compact consumer boards
- Height usually decides. Work back from the clearance available, then confirm the chosen size band still meets both current ratings.
Noise-sensitive equipment
- Molded parts are inherently shielded and quieter than open wirewound. Verify audible noise at your switching frequency on the real assembly.

カテゴリー概要
Molded versus wirewound, and which current rating binds
Two questions decide most molded inductor selections: whether the construction is right for the design, and which of the two current figures limits you.
型番が決まっている場合は、サンプルまたは見積もりを依頼。
What molded construction changes
The winding is encased in a magnetic composite rather than wound on an exposed core. That makes the part self-shielding, so it couples less into neighbouring traces, and it damps the movement that causes audible buzz. It also gives a softer saturation curve, where inductance falls gradually rather than collapsing.
IRMS and ISAT do different jobs
IRMS is a thermal limit: the continuous RMS current that produces the stated temperature rise. ISAT is a magnetic limit: the current at which inductance has dropped by a stated percentage. A design has to satisfy both. Steady-state load is checked against IRMS, and peaks including startup inrush against ISAT.
Height is usually the real constraint
Within the same footprint, a taller body has more winding volume, which means lower DC resistance and higher current for the same inductance. The range spans from one millimetre high up to more than twelve. In practice the clearance over the converter often decides the series before any electrical parameter does.
よくあるご質問
Molded power inductor questions engineers ask
Answers cover molded versus wirewound, IRMS against ISAT, and shielding.
What is WHYTA for?
Designs where the height available over the converter is the binding constraint. Bodies go down to about 1.0 millimetre high on a 4.4 by 4.2 millimetre footprint, which fits under covers and in slim assemblies where the standard range will not. Inductance runs from 0.1 to about 22 microhenries.
What do I give up by going low profile?
Winding volume, which means higher DC resistance for a given inductance and lower current capability than a taller body of the same footprint. RMS current tops out around 25 amps across the range. If your load needs more, a taller body is required and the height budget has to change.
How low can the height go?
Down to about 1.0 millimetre on the smallest footprint. Above that the range steps through roughly 1.3, 1.6, 1.8, 2.2 and 2.8 millimetre heights across several footprints, so there is usually a choice within a given clearance. Read the exact dimensions from the datasheet.
Are low profile parts still self-shielded?
Yes. The molded construction encases the winding in magnetic composite regardless of the body height, so the shielding and the low audible noise behaviour carry across the whole family. What changes with height is the current capability and the DC resistance, not the construction.
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 height clearance, output current, switching frequency and ripple budget, and a sales engineer will shortlist candidates.
