SMD Inductors
Large-Current Power Inductors MPCH
Overview
Applications
The KEMET MPCH metal composite inductors are designed
for use in power supplies with ripple currents up to 32 A.
These inductors offer superior permeability when compared
to technologies based on ferrite cores.
• Switching DC-DC power supplies
• Notebook computers
• Tablets
• Embedded computer systems
• Servers and storage
• HDTVs
The flat wire design allows for high efficiency under high
current loads.
Benefits
• Metal composite powder
• Operating temperature up to +125°C
• High current
• High permeability
• Low DCR
• Low acoustic noise

Environmental Compliance
All KEMET SMD Inductors are RoHS compliant.
Handling Precautions
Inductors should be stored in normal working environments. While the inductors themselves are quite robust in other
environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and
long term storage.
KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 70%
relative humidity. Atmospheres should be free of chlorine and sulfur bearing compounds. Temperature fluctuations should
be minimized to avoid condensation on the parts.
For optimized solderability, inductors’ stock should be used promptly, preferably within six months of receipt.

Export Control
For customers in Japan
For products which are controlled items subject to the “Foreign Exchange and Foreign Trade Law” of Japan, the export
license specified by the law is required for export.
For customers outside Japan
Inductors should not be used or sold for use in the development, production, stockpiling or utilization of any conventional
weapons or mass-destruction weapons (nuclear, chemical, biological weapons or missiles), or any other weapons.
