Offering two inductors in one 4032 package, Vishay Intertechnology has announced that the automotive-grade IHLD-4032KB-5A is the industry's first dual inductor to operate up to +155°C. The device is optimised for automotive and commercial class D amplifier circuits, where it reduces board space requirements and offers improved performance compared to multiple discrete inductors.

The IHLD-4032KB-5A's optimal design produces high-quality sound, low distortion and low coupling for minimal cross-talk between inductors.

Built on Vishay's IHLP technology, the AEC-Q200-qualified inductor offers a maximum DCR of 32.6-107mΩ, inductance of 10-33µH, rated current to 5.6 A 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.

Manufactured using a 100% lead-free shielded, composite construction package, the IHLD-4032KB-5A is specified for an operating temperature range from -55 +155°C, with high resistance to thermal shock, moisture, mechanical shock and vibration.

Samples and production quantities of the dual inductor are available now, with lead times of 10 to 12 weeks for large orders.
