The new Vishay Automotive-Grade IHLD Low-Profile, High-Current Dual Inductors saves space and provides better performance in Class D amplifiers.

Vishay Dual Inductors Offer High-Temperature Operation to +155°C.
The Automotive Grade IHLD-3232HB-5A saves board space by combining two inductors in one 9.75mm by 9.14mm package. 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 has high resistance to thermal shock, moisture, mechanical shock, and vibration. The Automotive Grade IHLD-4032KB-5A offers max. DCR from 32.6mΩ to 107mΩ, inductance from 10µH to 33µH, rated current to 5.6A, and a frequency range up to 1MHz. The device handles high transient current spikes without saturation and has excellent temperature stability for inductance and saturation over its operating range. Its optimal design produces high-quality sound, low distortion, and low coupling for minimal cross-talk between inductors. Both the IHLD-3232HB-5A and IHLD-4032KB-5A are optimized for automotive and commercial class D amplifier circuits, where the devices reduce board space requirements and offer improved performance over multiple individual inductors. They both have an operating temperature range of -55°C to +155°C.


◾Two IHLP®-style inductors placed vertically in one board-space saving package
◾AEC-Q200 qualified
◾Two sizes available: 3232 and 4032
◾Soft saturation provides more stable inductance across varying volume levels for lower THD (total harmonic distortion)
◾Excellent L (inductance) vs. temperature stability (~ 100ppm/°C) for lower THD across a wide range of operating temperatures
◾Low coupling (average < 5%) between adjacent inductors reduces crosstalk and noise
◾Optimal design enables high-quality audio with low distortion


◾Automotive and commercial class D amplifier circuits



◾DC/DC converter applications where two inductors are needed and board space is at a premium
