Pulse Electronics High-Efficiency Ultra-Low DCR Power Bead Inductors
Pulse Electronics High-Efficiency Ultra-Low DCR Power Bead Inductors are designed for the latest multi-phase and Point-of-Load (PoL) architectures for server, graphics, and high power FPGAs. These inductors provide ultra-low DCR, ranging from 0.125mΩ to 0.81mΩ. They feature low-loss ferrite cores and an optimized structure to ensure high efficiency and maximum power density. The peak current rating ranges from 37Apk to more than 100Apk while inductance ranges from 55nH to 1000nH. Pulse Electronics High-Efficiency Ultra-Low DCR Power Bead Inductors are available in a variety of footprints, from 5.5mm x 5.7mm to 10.8mm x 8.2mm with heights from 4.6mm to 12mm.
