SMD Inductors(Coils) For Power Line(Wound, Magnetic Shielded)
SLF Series SLF12555
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. www.DataSheet4U.com SPECIFICATIONS
