(1/2)
Inductors
For Power Line
SMD
FEATURES
• The SLF series are characterized by low profile, low DC
resistance, and high current handling capacities.
• Because they are magnetically shielded, these parts can be
used in high-density mounting configurations.
• Flat bottom surface ensures secure, reliable mounting.
• Provided in embossed carrier tape packaging for use with
automatic mounting machines.
APPLICATIONS
Portable telephones, personal computers, hard disk drives, and
other electronic equipment.
