One world. One KEMET
Applications
• Switching DC-DC power supplies
• Notebook computers
• Tablets
• Embedded computer systems
• HDTVs
• DVD and BluRay players
Overview
The KEMET MPCG metal composite inductors are
designed with a very low loss core and at wire design,
which enables very high eciency at high ripple currents.
The core material used is ideal for high switching
frequency applications.
