Low-profile high-current inductors

12 July 2006 Passive Components

Vishay Intertechnology is extending its IHLP family of low-profile, high-current inductors with new devices in the 2525-size footprint offering inductance values from 10 μH down to 0,56 μH.

Claimed to have the lowest DCR mH for their respective package sizes, the new IHLP inductors serve as high-performing, space- and power-saving solutions for voltage regulator module and DC-DC converter applications, high-current power supplies and point of load converters, distributed power systems, and FPGAs.

The IHLP2525EZ01 inductors measure 6,47 x 6,86 mm with a maximum height of 5,0 mm. They occupy the standard 2525 footprint shared by lower-profile IHLP devices while providing higher rated current and lower DCR values. The devices are specified for saturation currents ranging from 4,5 A to 12 A, typical DCR values ranging from 3,4 mΩ to 67,9 mΩ, and maximum DCR values ranging from 3,6 mΩ to 71,3 mΩ. Standard inductance tolerance is ±20%.

The devices handle high transient current spikes without hard saturation and operate at a frequency under 1 MHz. They are packaged in an RoHS-compliant shielded, composite construction that reduces buzz noise to ultra-low levels. They are specified for a -55 to +125°C with high resistance to thermal shock, moisture, mechanical shock, and vibration.
