Vishay Intertechnology Commercial IHSR High Temperature Inductor Delivers Ultra Low DCR for Multi-Phase Power Supplies
November 17 2021 - 1:38PM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new
commercial IHSR high temperature inductor in the 7.4 mm by 6.6 mm
by 3.0 mm 2525 case size. Designed for multi-phase, high current
power supplies and filters, the Vishay Dale IHSR-2525CZ-51 offers a
50 % reduction in DCR over typical power inductors, excellent
inductance stability over the entire operating temperature range,
and soft saturation compared to ferrite solutions.
Based on Vishay’s popular IHLP® technology, the inductor
released today is optimized for energy storage in DC/DC converters
up to 10 MHz and high current filtering applications up to the SRF
of the inductor. With its high operating temperature up to +155 °C,
the device is designed for filtering and DC/DC conversion in
notebooks, desktops, and servers; POL converters; graphics cards;
distributed power systems; and FPGAs.
The IHSR-2525CZ-51’s low typical DCR of 0.38 mΩ and inductance
of 0.056 µH allow for higher current density than competing
technologies, while its 3 mm profile enables slimmer end products.
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
and handles high transient current spikes without saturation. The
device is RoHS-compliant, halogen-free, and Vishay Green.
