Automotive-grade dual inductors offer high temperature operation and saves board space

Vishay’s automotive-grade IHLD dual inductors, now available from TTI Europe, offer high temperature operation up to +155C. The new low-profile and high-current devices save board space by combining two inductors in one 9.75mm x 9.14mm package and provide a very good performance in Class D amplifiers. Built on the company’s IHLP technology, the AEC-Q200-qualified IHLD-3232HB-5A inductor pair offers maximum DCR from 29.2mohm up to 159.43mohm, inductance from 5µH up to 33µH, and rated current up to 6A. 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 component offers max. DCR from 32.6mohm up to 107mohm, 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 -55C up to +155C.
