This release in:

MALVERN, Pa.Feb. 28, 2019 — Vishay Intertechnology, Inc. (NYSE: VSH) today 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 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 released today 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 mW 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.
