EMC Components

ACF Series ACF321825, 451832 Types

3-Terminal Filters for Signal 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.

• Because they can be mounted on edge, the ACF series are

ideal for high-density circuit configurations.

• Available for reflow soldering.

• It is a product conforming to RoHS directive.
