A new series of low-profile surface-mount inductors in the 2525 package size has been released by Vishay Intertechnology Inc. Devices in the IHLP-2525AH-01 series are specified for saturation currents up to 40A and offer typical DCR values as low as 3 m? in a package measuring 1.8mm high.

According to the company, these new additions to the IHLP series provide lower DCR values than conventional solutions. They offer higher-performing, space- and power-saving solutions for dc-to-dc converter and energy storage applications in end products including computers, servers, telecom, and automotive electronics, as well as in high-current power supplies and point of load (POL) converters, distributed power systems and FPGAs, added Vishay.

In addition to their 1.8mm height profile, the surface-mount inductors feature a compact footprint with dimensions of 6.47-by-6.86mm. The series' saturation current ranges from 8A to 40A, and typical DCR values range from 3 m? to 76.6 m? over a standard inductance range of 0.1?H to 4.7?H, with a tolerance of 20 percent. At full rated current, IHLP inductors feature an inductance drop of less than 20 percent, a lower inductance roll-off than is provided by ferrite materials.

The IHLP-2525AH-01 inductors also handle high transient current spikes without saturation and operate over a frequency range up to 5MHz. Packaged in a 100 percent Pb-free, shielded, composite construction that reduces noise buzz to ultra-low levels, the new devices are specified for an operating temperature range of -55C to 125C with high resistance to thermal shock, moisture, mechanical shock and vibration.

Samples and production quantities are already available. Lead time for production quantities is 8 to 10 weeks.
