Vishay Intertechnology introduced recently the IHLD-4032KB-5A, the first of its new IHLD family of dual inductors. The IHLD-4032KB-5A features two inductors in a single 4032 package and operates at a temperature range to +155C.

The Vishay Dale inductor is optimised for automotive and commercial class D amplifier circuits, where the device reduces board space requirements and offers improved performance over using 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.

Vishay's IHLD-4032KB-5A

Built on Vishay's IHLP technology, the AEC-Q200-qualified inductor offers maximum DCR from 32.6m to 107m, inductance from 10?H to 33?H, 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. Manufactured using a 100 per cent lead (Pb)-free shielded, composite construction package, the IHLD-4032KB-5A is designed for an operating temperature range of 55C to +155C, 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 10 to 12 weeks for large orders.
