FEATURES
PRODUCT IDENTIFICATION
• 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.
