Vishay has announced a low-profile, high-current inductor in the 2020 case size. The compact IHLP-2020BZ-01 offers a 5.18-mm by 5.49-mm footprint and ultra-low 2.0-mm profile, with a high maximum frequency and standard inductance values from 0.1μH through 10μH.

With a frequency range up to 5MHz, the new IHLP inductor serves as a high-performing, space- and power-saving solution for voltage regulator module (VRM) and dc-to-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive systems; low-profile, high-current power supplies and point of load (POL) converters; distributed power systems; and field-programmable gate arrays (FPGAs).

The IHLP-2020BZ-01 offers an inductance range from 0.10μH to 10μH, a saturation current range from 4A up to 45A, typical DCR from 3.6mΩ to 184.0mΩ, and maximum DCR from 3.9mΩ to 199.0mΩ.

The new inductor handles high transient current spikes without hard saturation. Packaged in an RoHS-compliant, 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the new device is specified for an operating temperature range of -55°C to +125°C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
