New commercial and automotive grade space-saving power inductors

Vishay Intertechnology, Inc. has introduced two new power inductors in the 2.5mm x 2mm x 1.2mm 1008 case size. The commercial IHLL-1008AB-1Z and automotive grade IHLP-1008ABEZ-5A attain the same performance as the next-smallest IHLP inductor in a 55% smaller footprint while delivering higher operating temperatures up to +165C, a wider range of inductance values, and lower DCR.

Supplying inductance values from 0.33µH to 4.7µH, the IHLL-1008AB-1Z's terminals are plated on the bottom only, allowing a smaller land pattern for more compact board spacing. The IHLP-1008ABEZ-5A's terminals are plated on the bottom and sides, forming a solder fillet that adds mounting strength against high mechanical shock while simplifying solder joint inspection. The AEC-Q200 qualified device provides reliable performance up to +165C, which is 10C higher than the nearest competing composite inductor, while its typical DCR down to 12mOhm is 15% lower.

Offering enhanced performance over ferrite-based technologies, the devices feature a robust powdered iron body that completely encapsulates their windings – eradicating air gaps and magnetically shielding against crosstalk to nearby components – while their soft saturation curve delivers stability across the whole operating temperature and rated current ranges. The inductors' low DCR and high current handling are results of their flat wire coil, which directly terminates and forms the leads of the inductor, eradicating the necessity for a lead frame. Precision laser stripping, followed by an electrode plating process at the leads, ensures ease of solderability and the capability to withstand repeated thermal cycling for maximum reliability.

The devices are designed for DC-DC converters, noise suppression, and filtering in various applications. The IHLP-1008ABEZ-5A is ideal for automotive infotainment, navigation, and braking systems; ADAS, LiDAR, and sensors; and engine control units. The IHLL-1008AB-1Z is aimed at CPUs, SSD modules, and data networking and storage systems; industrial and home automation systems; TVs, soundbars, and audio and gaming systems; battery-powered consumer healthcare devices; medical devices; telecom equipment; and precision instrumentation.

Packaged in a 100% lead (Pb)-free shielded, composite construction that decreases buzz to ultra-low levels, the devices offer high resistance to thermal shock, moisture, and mechanical shock and handle high transient current spikes without saturation. They are RoHS-compliant, halogen-free, and Vishay Green.
