Vishay Intertechnology, Inc. today introduced the first device in its new IHLD series of low-profile, high-current dual inductors. Offering two inductors in one 4032 package, the space-saving automotive-grade IHLD-4032KB-5A is the industry’s first dual inductor to offer a high operating temperature range to +155 degrees C. 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 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.

Built on Vishay’s IHLP® technology, the AEC-Q200-qualified inductor offers maximum DCR from 32.6 mΩ to 107 mΩ, inductance from 10 µH to 33 µH, rated current to 5.6 A, and a frequency range up to 1 MHz. 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 (Pb)-free shielded, composite construction package, the IHLD-4032KB-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.
