SMD Multilayer Power Inductors – MP Series
Multilayer Power Inductors
The MPx 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.
Features
RoHS, Halogen Free and REACH Compliance
Small size
Low profile
High current
Magnetically shielded configuration allowing for high density
mounting
Applications
DC-DC converters
Power modules
Cellular phones
DSC, PND, DVD
Wireless card and other electronic devices
