SMD Shielded Power Inductors - SDT Series
SDT Series
SDT Series is the ultimate cost effective and miniature power inductors.
They are constructed of materials specially developed for surface mount
applications to ensure the best possible reliability and ease of using and
handling.
Because
of
their
“swinging”
inductance
vs.
current
characteristics, the SSL0402 Series supports used as ultra high
inductance at zero or low current.
Features
RoHS compliant
High inductance shielded power inductors
Functions equally well in filter and smoothing circuit applications
Applications
Board mounted DC-DC converters
Miniature power supplies and voltage multiplying circuits
