LC Series • Miniature Low Cost Toroidal Inductors
LC Series surface mount toroidal inductors are designed for
use in applications where energy storage is required for
maintenance of a highly stable inductance when a rapid change
in load current occurs. These inductors are excellent for filtering
high frequency signals while supporting a substantial DC
current as well as for AC ripple, switch mode power supplies
and for use with DC-DC Converters.
