Vishay launched two new IHLP low-profile, high-current inductors in the 1212 case size. The compact IHLP-1212AB-11 and IHLP-1212AE-11 offer a 3.0 mm by 3.6 mm footprint with ultra-low profiles of 1.2 mm and 1.5 mm respectively. With a high maximum 1 MHz frequency and standard inductance values from 0.22 µH through 1.0 µH, IHLP-1212AB-11 and IHLP-1212AE-11 serve as high-performing, space- and power-saving solutions for voltage regulator module (VRM) and DC/DC converter applications in end products including next-generation mobile devices, notebooks, desktop computers, graphics 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-1212AB-11 offers an inductance range from 0.22 µH to 0.56 µH, a saturation current range from 6.7 A to 9.3 A, typical DCR from 9.5 mΩ to 18.7 mΩ, and maximum DCR from 11.4 mΩ to 22.0 mΩ. The IHLP-1212AE-11 offers an inductance range from 0.22 µH to 1.0 µH, a saturation current range from 5.3 A to 9.0 A, typical DCR from 9.5 mΩ to 29.5 mΩ, and maximum DCR from 11.4 mΩ to 33.0 mΩ.

The new inductors handle 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 devices are specified for an operating temperature range of 55 °C to + 125 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
