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.

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.
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.
Because of their “ swinging “ inductance vs. current characteristics, the SSL0402 Series can be used
as ultra high L inductors at zero or low current.
