Vishay Intertechnology Automotive Grade IHSR High Temperature Inductor Delivers Ultra Low DCR, High Current Filtering in 2525 Case Size for Multi-Phase Power Supplies
December 01 2021 - 1:00PM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new
AEC-Q200 qualified 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 in automotive under the hood and
ADAS applications, the Vishay Dale IHSR-2525CZ-5A offers a 50 %
reduction in DCR over typical power inductors and excellent
temperature stability for inductance and saturation compared to
ferrite solutions.
The Automotive Grade 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 engine and transmission control
units, ADAS microprocessors, and entertainment / navigation
systems, in addition to noise suppression for motors, windshield
wipers, power mirrors and seats, and heating and ventilation
blowers.
The IHSR-2525CZ-5A’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.
