Compact Power Inductors for Commercial and Automotive Applications

The latest offerings from Vishay Dale, the commercial IHLL-1008AB-1Z and Automotive Grade IHLP-1008ABEZ-5A power inductors, have been designed to deliver exceptional performance in a compact form factor. These inductors stand out by achieving the same level of performance as the next-smallest IHLP® inductor while occupying 55% less space. Additionally, they boast higher operating temperatures of up to +165 °C, a wider range of inductance values, and lower DCR.

With inductance values ranging from 0.33 µH to 4.7 µH, the IHLL-1008AB-1Z features terminals plated on the bottom only, allowing for a smaller land pattern that facilitates more compact board spacing. On the other hand, the IHLP-1008ABEZ-5A comes with terminals plated on both the bottom and sides, enabling the formation of a solder fillet that enhances mounting strength against mechanical shock and simplifies solder joint inspection.

Both devices, which are AEC-Q200 qualified, offer reliable performance at temperatures up to +165 °C, surpassing the competition with a 10 °C higher threshold. The IHLP-1008ABEZ-5A's typical DCR can go as low as 12.0 mΩ, representing a 15% reduction compared to similar composite inductors. These inductors are built to outperform ferrite-based technologies, featuring a robust powdered iron body that encapsulates their windings entirely, eliminating air gaps and providing magnetic shielding against crosstalk.

Designed for a variety of applications, the Vishay Dale power inductors cater to the needs of DC/DC converters, noise suppression, and filtering requirements across different industries. The IHLP-1008ABEZ-5A is particularly well-suited for automotive applications such as infotainment systems, navigation devices, braking systems, ADAS, LiDAR, sensors, and engine control units. On the other hand, the IHLL-1008AB-1Z is intended for use in CPUs, SSD modules, data networking and storage systems, industrial and home automation setups, TVs, soundbars, audio and gaming systems, consumer healthcare devices, medical equipment, telecom gear, and precision instrumentation.

Both the IHLL-1008AB-1Z and IHLP-1008ABEZ-5A are packaged in a 100% lead (Pb)-free shielded, composite construction that minimizes buzz to ultra-low levels. These inductors are engineered to withstand thermal shock, moisture, and mechanical stress, and are capable of handling high transient current spikes without saturation. Furthermore, they are RoHS-compliant, halogen-free, and Vishay Green, aligning with modern environmental standards.
