SMD Inductors
Metal Composite Power Inductors MPX
Overview
The KEMET MPX metal composite inductors are ideal
for use in DC to DC switching power supplies, as power
inductors as well as EMI filter inductors. The metal
composite core has high saturation characteristics
maintaining function in rush current mode and
characterized by temperature stable inductance.
Applications
Consumer and commercial power applications such as:
• High frequency DC-DC converters, including WBG GaN
applications
• PCs and servers
• Points of loads (POL)
• Field-programmable gate arrays (FPGA)
• Battery powered regulators
Benefits
• Metal composite powder
• Shielded construction, SMD configuration
• Inductance range from 0.10 – 100.00 µH
• Operating temperature up to +155°C
• Low acoustic noise
• Low magnetic flux leakage

The first two digits
represent the inductance
value. The third digit
inidcates the number of
zeros to be added.
R = decimal point
Examples:
100 = 10.00 μH
R68 = 0.68 µH
1R5 = 1.50 µH
101 = 100.00 µH
