Vishay Intertechnology introduces 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 onboard space.

Features

  • Optimized for energy storage in DC/DC converters up to 5 MHz
  • provides excellent attenuation of noise in high current filtering applications up to the SRF of the inductor
  • Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra-low levels
  • High resistance to thermal shock, moisture, and mechanical shock
  • Low DCR of 0.24 mOhm
  • Compact 10 mm by 6 mm by 10 mm 4024 case size
  • Vertical-mount design
  • A high-temperature operation to +155 °C
  • Handle high transient current spikes without saturation
  • RoHS-compliant

Applications

  • Energy storage in DC/DC converters and high current filtering in servers and desktop PCs
  • high current POL converters
  • multi-phase, high current power supplies
  • battery-powered devices
  • distributed power systems
  • FPGAs
