| (1/2) 001-01 / 20030823 / e9613_acf.fm EMC Components ACF Series ACF321825, 451832 Types 3-Terminal Filters for Signal Line and DC Power Line SMD FEATURES * The ACF series are T-type EMC filters incorporating ferrite chip beads and multilayer ceramic chip capacitors. * The external structure consists entirely of ferrite, enabling these parts to achieve superior attenuation characteristics despite their extremely compact dimensions. ACF321825 TYPE SHAPES AND DIMENSIONS/CIRCUIT DIAGRAM 3.20.3 Terminal electrode * Because they can be mounted on edge, the ACF series are ideal for high-density circuit configurations. * Available for reflow soldering.
