Power‑efficient, ultra‑compact inductors built for audio, medical, new‑energy and industrial equipment.
Get Free Quote in 24 hAverage market price for Class d inductors in the U.S. exceeds $2.80 per unit, a 35 % increase over 2022 levels. This cost pressure forces you to either cut margins or postpone critical product launches.
Over 42 % of buyers report failure rates above 0.7 % within the first 12 months, leading to warranty claims and brand damage.
Typical lead times of 45‑60 days clash with agile product‑development cycles. When you need a specific inductance or a custom footprint, many suppliers lack transparent engineering support.
| Parameter | Typical Value | Unit | Compliance |
|---|---|---|---|
| Inductance (L) | 10 µH – 470 µH | µH | IEC 60068‑2‑1 |
| Current Rating (Imax) | 0.5 – 5 | A | UL 94 V‑0 |
| Q‑Factor | ≥ 30 (at 1 MHz) | – | ISO 9001 |
| Operating Temp. | ‑40 °C – +125 °C | °C | RoHS, REACH |
| Package Type | SMD, THT, Custom | – | CE, FCC |
