IHLP-1008ABEZ-5A and IHLL-1008AB-1Z Series Power Inductors

Vishay power inductors are offered in a 2.5 mm by 2.0 mm by 1.2 mm 1008 case size. The commercial IHLL-1008AB-1Z and automotive-grade IHLP-1008ABEZ-5A achieve the same performance as the next-smallest IHLP^® inductor in a 55% smaller footprint while offering higher operating temperatures to +165°C, a wider range of inductance values, and lower DCR. The IHLL-1008AB-1Z’s terminals are plated on the bottom only, enabling a smaller land pattern for more compact board spacing. The IHLP-1008ABEZ-5A’s terminals are plated on the bottom and sides, allowing for the formation of a solder fillet that adds mounting strength against high mechanical shock while simplifying solder joint inspection.

The IHLP-1008ABEZ-5A offers a +10°C higher operating temperature than the closest competing composite inductor, while its typical DCR is 15% lower. Offering improved performance over ferrite-based technologies, both devices feature a robust powdered iron body that completely encapsulates their windings, eliminating air gaps and magnetically shielding against crosstalk to nearby components, while their soft saturation curve provides stability across the entire operating temperature range. The inductors’ low DCR and high current handling are the results of their flat-wire coil, which directly terminates and forms the leads of the inductor, eliminating the need for a lead frame. Precision laser stripping, followed by an electrode plating process at the leads, ensures ease of solderability and the ability to withstand repeated thermal cycling for maximum reliability.
