YAGEO CORPORATION SMD INDUCTOR/BEADS
SMD Power Inductors
SDT0402 Series
AppLICATIonS
Board mounted DC-DC converters
Miniature power supplies, and voltage multiplying circuits.
These inductors are designed for a wide variety of applications including board mounted DC-DC con-
verters, miniature power supplies, and voltage multiplying circuits.They function equally well in filter
and smoothing circuit applications.
fEATURES
The Yageo SDT Series represents the ultimate in cost effective miniature power inductors.They are
constructed of materials specially developed for surface mount applications to ensure the best pos-
sible reliability and ease of using and handling.
Ultra high L and low current
Functions equally well in filter and smoothing cir-
cuit applications.
•Available in 2 sizes.
Because of their “ swinging “ inductance vs. current characteristics, the SSL0402 Series can be used
as ultra high L inductors at zero or low current.

• Note: YAGEO will start to release SDT Series
inductors with lead-free terminals which
meet SONY SS-00259's criteria for lead-free
product in Q2 of 2004, and YAGEO Internal
No will be changed to “N” as identification.
