PM52

SMT Power Inductors
Special Features
PM52 Series
• High current capacity
• Ferrite bobbin core
• Low core loss for high frequency power applications
• Compact size
• Large terminal surface for excellent PCB bonding
• Operating temperature -30 to +100 °C
• Tape & reel packaged 2000/reel
Typical Applications
• Notebook computers
• Battery chargers
• DC/DC converters
