Original Press Release:
New Vishay Intertechnology Automotive-Grade Dual Inductor in 3232 Package Saves Space in Class D Amplifiers
AEC-Q200-Qualified Device Offers High-Temperature Operation to +155 °C
MALVERN, Pa. – Vishay Intertechnology, Inc. (NYSE: VSH) today expanded its IHLD series of low-profile, high-current dual inductors with a new device in the 3232 case size. Offering a high operating temperature range to +155 °C, the automotive-grade IHLD-3232HB-5A saves board space by combining two inductors in one 9.75 mm by 9.14 mm package.
The Vishay Dale inductor released today is optimized for automotive and commercial class D amplifier circuits, where the device reduces board space requirements and offers improved performance over multiple individual inductors. In addition, the IHLD-3232HB-5A is designed for excellent inductance stability over temperature and DC current, providing high-quality sound and low harmonic distortion due to linear saturation performance. The inductor pair is designed with very low coupling for minimal crosstalk between inductors.
Built on Vishay's IHLP® technology, the AEC-Q200-qualified inductor pair offers maximum DCR from 29.2 mΩ to 159.43 mΩ, inductance from 5 µH to 33 µH, and rated current to 6.0 A. Other values are available upon request. Manufactured using a 100 % lead (Pb)-free shielded, composite construction package, the IHLD-3232HB-5A is specified for an operating temperature range of 55 °C to +155 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
Samples and production quantities of the new dual inductor are available now, with lead times of 11 weeks for large orders. Pricing for U.S. delivery in 10,000-piece quantities is $0.99 per pair of inductors.
