Closed Magnetic Circuit Core Type HF Series
FEATURES
• This series employs two outer magnetic path limbs design with
windings on the center magnetic path limb of double-square
shaped closed magnetic circuit ferrite core to reduce leakage
flux.
• This filter uses the same closed magnetic circuit core as a
toroidal core and therefore, even at its compact size, it offers
large inductance and suppresses noise up to in high frequency
ranges.
