High Saturation Inductor Features Low DCR, High Current Density

Vishay Intertechnology enlarges its IHSR series high saturation commercial inductors with a compact, 4 mm x 4 mm 1616 case size component. Designed for multi-phase, high current power supplies, the IHSR-1616AB-01 is said to offer a 50 % reduction in 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 component 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.
