TF SERIES
FEATURES
This series uses a high permeability toroidal ferrite core and
therefore provides large inductance with a little number of turns.
Therefore its stray capacity is small and it keeps the impedance
required to effectively suppress high frequency noises.
Products mounted on a base with fixed leads are easy to insert
to circuit boards.
