SMD Multilayer Power Inductors – BKPA/BKPB/BKPE Series
Multilayer Power Inductors
The BKPx Series is a miniature type of multilayer power inductor
constructed using low-loss ferrite material to support high-speed
switching frequencies. The compact size and high efficiency is ideal for
DC-DC converter applications in space-limited boards.
