Malvern, Pa. Vishay Intertechnology Inc. has expanded its IHLP family with the release of the IHLP-4040DZ-01 and IHLP-4040DZ-11 low-profile, high-current inductors, which feature high maximum frequencies and low inductance values.
Offering very low direct current resistance (DCR) and the highest inductance for their respective package sizes, the new IHLP inductors may be used for voltage regulator module (VRM) and DC/DC converter applications in end products such as next-generation mobile devices, notebook and desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive systems. They may also be used in power supplies and point of load (POL) converters, distributed power systems, and field-programmable gate arrays (FPGAs).
The IHLP-4040DZ-11 offers a maximum frequency of 1.0 MHz, while the IHLP-4040DZ-01 features a maximum frequency of 5.0 MHz. Both devices offer inductance values down to 0.19 uH.
The IHLP-4040DZ-11 offers an inductance range from 0.19 uH up to 100 uH, a saturation current range from 2.25 A up to 46 A, a typical DCR from 0.70 milliohms (mΩ) to 249.0 mΩ, and maximum DCR from 0.80 mΩ to 270.0 mΩ.
The IHLP-4040DZ-01 offers an inductance range from 0.19 uH up to 10 uH, a saturation current range from 12.0 A up to 90 A, a typical DCR from 0.875 mΩ to 33.20 mΩ, and maximum DCR from 0.95 mΩ to 36.5 mΩ.
With compact dimensions of 0.405 in. x 0.453 in. (10.3 mm x 11.5 mm) and a very low height profile of 0.158 in. (4.0 mm), the IHLP-4040DZ-01 and IHLP-4040DZ-11 inductors occupy the standard 4040 footprint shared by lower-profile IHLP devices while providing higher rated current and lower DCR values.
In addition, the inductors handle high transient current spikes without hard saturation. Packaged in an RoHS-compliant, 100% lead-free (Pb-free) shielded, composite construction that reduces buzz noise to ultra-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.
