Low-Profile, Surface-Mount Inductors

6/3/2003 Low-Profile, Surface-Mount Inductors Vishay Intertechnology Inc.’s IHLP-5050FD-01 series is a low-profile, high-current inductor with typical DCR values as low as 0.47 mΩ and low losses at frequencies up to 5 MHz.

This latest addition to the patented Vishay Dale IHLP family of compact, surface-mount inductors is designed to provide a higher-performing, power- and space-saving solution for dc-dc converter and energy storage applications in end products, including computers, servers, telecom, and automotive electronics.

Devices in the IHLP-5050FD-01 series are offered in a surface-mount package measuring just 0.508 in. (12.9 mm) × 0.520 in. (13.2 mm), with a height profile of 0.256 in. (6.5 mm). The inductor's high saturation current ranges from 30A to 120A, and its maximum DCR values range from 0.50 mΩ to 11.2mΩ.

Standard inductance values range from 0.10 µH to 4.7 µH, with a tolerance of ±20%. At full rated current, they feature an inductance drop of less than 20%—a lower inductance roll-off than is provided by ferrite materials.

The IHLP-5050FD-01 inductors feature a self-shielded package and meet military specifications for resistance to thermal shock, moisture, mechanical shock, and vibration.
