FERRITE CHIP EMI COMPONENTS
FERRITE CHIP EMI FILTERS ACF SERIES
FEATURES
SHAPES AND DIMENSIONS
The ACF series is a T-type EMI filter family with 2 beads
and 1 capacitor packed into 1 single chip.
High attenuation in a small case size is possible due to
a magnetic shield structure.
L
Even larger attenuation is possible by using a circuit with
a stabilized ground.
ACF3218 series
18 different suppressors are available, completely
covers 11~700MHz. (25dB attenuation)
