## **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. 

## **TEMPERATURE RANGES** 

||Operating|–25 to +85°C|
|---|---|---|
|**PACKAGING STYLE AND QUANTITIES**|||
||Packagingstyle|Quantity|
||Taping|1000pieces/reel|



- Because they can be mounted on edge, the ACF series are ideal for high-density circuit configurations.
