ACF321825 Datasheet | TDK Corporation

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 pact 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.
