YAGEO CORPORATION SMD INDUCTOR / BEADS
SMD Power Inductors
STD1109 Series
Yageo SMD power inductors are best designed for noise / EMI / RFI filters for surface mounting
applications.
These components contain tremendous electrode straight, solder heat resistance and outstanding
solderability. These products are specially designed for flow, reflow and wave soldering required for
surface mounting applications.
