www.DataSheet4U.com (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 3.2± 0.3 Terminal electrode Because they can be mounted on edge, the ACF series are ideal for high-density circuit configurations. Available for reflow soldering.
