Vishay Extends IHLP Family of Low-Profile, High-Current Inductors

With a frequency range up to 1.0 MHz, the new IHLP-1212BZ-11 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, 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-1212BZ-11 offers an inductance range from 0.22 µH to 1.5 µH, a saturation current range from 4.0 A up to 7.5 A, typical DCR from 9.5 mΩ to 27.0 mΩ, and maximum DCR from 11.4 mΩ to 32.0 mΩ.

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 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.
