Automotive-Grade Dual Inductor for Class D Amplifiers

Vishay Intertechnology, Inc. 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 degrees 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 29.2mΩ to 159.43mΩ, inductance from 5µH to 33µH, and rated current to 6.0A. 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 to +155 degrees C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
