Automotive grade inductors save board space

Now available in Europe through TTI are Vishay’s automotive-grade IHLD dual inductors offering high temperature operation up to +155°C. The new low-profile and high-current devices save board space by combining two inductors in one 9.75mm by 9.14mm package and provide a very good performance in Class D amplifiers.

Built on Vishay's IHLP technology, the AEC-Q200-qualified IHLD-3232HB-5A inductor pair offers maximum DCR from 29.2mΩ up to 159.43mΩ, inductance from 5µH up to 33µH, and rated current up to 6.0A. Other values are available upon request.

Manufactured using a 100% lead (Pb)-free shielded, composite construction package, the IHLD-3232HB-5A part benefits from high resistance to thermal shock, moisture, mechanical shock, and vibration.

The automotive-grade IHLD-4032KB-5A component offers max. DCR from 32.6mΩ up to 107mΩ, inductance from 10µH up to 33µH, rated current up 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 components have been optimised for automotive and commercial class D amplifier circuits, where they offer improved performance over multiple individual inductors. They both have an operating temperature range of -55°C up to +155°C.
