High current inductor delivers improved saturation and temperature stability

Vishay Intertechnology has introduced a new high current inductor that delivers 50% lower DCR than typical power inductors for enhanced efficiency in high-frequency DC-DC converters. Utilising materials and construction similar to the IHLP, the Vishay Dale IHVR-4024KE-51 also provides exceptional saturation and temperature stability. Offered in a compact 10mm x 6mm x 10mm 4024 case size, the device allows high current density, while its vertical-mount design saves board space.

Providing high-temperature operation to +155C, the inductor is optimised for energy storage in DC-DC converters up to 5MHz. It delivers excellent attenuation of noise in high current filtering applications up to the SRF of the inductor. Applications for the device covers servers and desktop PCs; high current POL converters; battery-powered devices; multi-phase, high current power supplies; distributed power systems; and FPGAs.

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