Vishay Intertechnology high saturation IHSR inductor features low DCR, high current density for multi-phase power supplies

04 March 2019

Vishay Intertechnology Inc. has expanded its IHSR series of high saturation commercial inductors with a new device in the compact 4 mm by 4 mm 1616 case size. Designed for multi-phase, high current power supplies and filters in computer, industrial and telecom applications, the Vishay Dale IHSR-1616AB-01 offers a 50% reduction in DC resistance (DCR) over typical power inductors and standard DCR tolerance of 5%, with 3% tolerance available for more accurate current sensing.

With a frequency range up to 5 MHz, the device is optimized for energy storage in DC/DC converters and high current filtering up to the self-resonant frequency (SRF) of the inductor (see table below). Applications include notebooks, desktop PCs and servers; low profile, high current power supplies and filters; and DC/DC converters for distributed power systems.

The IHSR-1616AB-01's low typical DCR down to 1.15 mΩ and inductance up to 0.068 µH allow for higher current density than competing technologies, while its low 1.2 mm profile enables slimmer end products. The inductor offers high-temperature operation to 125° C, rated current to 62 A, and handles high transient current spikes without saturation.

Packaged in a 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the inductor offers high resistance to thermal shock, moisture and mechanical shock. The IHSR-1616AB-01 is RoHS-compliant, halogen-free and Vishay Green.

Samples and production quantities of the new inductor are available now, with lead times of 12 weeks for large orders.
