SMD Inductors(Coils)
For Power Line(Wound, Magnetic Shielded)

SLF Series SLF12565

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.

Rated current: Value obtained when current flows and the temperature has risen to 40°C or when DC current flows and the nominal value of inductance
has fallen by 10%, whichever is smaller.
