Vishay Intertechnology High Current Inductor Delivers Improved Saturation and Temperature Stability

Vishay IHVR-4024KE-51

Vertical-Mount IHVR-4024KE-51 Device in Compact 4024 Case Size Offers 50 % Lower DCR Than Typical Power Inductors While Saving Board Space

Vishay Intertechnology introduced a new high current inductor that provides 50% lower DCR than typical power inductors for improved efficiency in high frequency DC/DC converters. Using materials and construction similar to the IHLP, the Vishay Dale IHVR-4024KE-51 also boasts excellent saturation and temperature stability. Available in the compact 10 mm by 6 mm by 10 mm 4024 case size, the device enables high current density, while its vertical-mount design saves on board space.

Vishay - IHVR-4024KE-51

Featuring high temperature operation to +155 °C, the inductor is optimized for energy storage in DC/DC converters up to 5 MHz and provides excellent attenuation of noise in high current filtering applications up to the SRF of the inductor. Applications for the IHVR-4024KE-51 will include servers and desktop PCs; high current POL converters; multi-phase, high current power supplies; battery-powered devices; distributed power systems; and FPGAs.

Packaged in a 100% lead (Pb)-free shielded, composite construction that reduces buzz to ultra low levels, the RoHS-compliant inductor offers high resistance to thermal shock, moisture, and mechanical shock, and handles high transient current spikes without saturation.
