## **3-terminal Filters(SMD) For Signal Line** 

## **Conformity to RoHS Directive** 

## ACF Series  ACF321825, 451832 Types 

## **FEATURES** 

- The ACF series consists of products with superior attenuation characteristics, in which the T-type filter circuit is magnetically shielded with ferrite. 

- The series offers even greater attenuation characteristics when used in a stable circuit on the ground. 

- The ACF series is ideal for high-density circuit design, since the series is vertically mounted and does not require much mounting space. 

- Available for reflow soldering. 

- It is a product conforming to RoHS directive.

## **HANDLING AND PRECAUTIONS** 

   - Before soldering, be sure to preheat components. The preheating temperature should be set so that the temperature difference between the solder temperature and product temperature does not exceed 150°C. 

   - After mounting components onto the printed circuit board, do not apply stress through board bending or mishandling. 

   - The inductance value may change due to magnetic saturation if the current exceeds the rated maximum. 

   - Do not expose the inductors to stray magnetic fields. 

   - Avoid static electricity discharge during handling. 

   - When hand soldering, apply the soldering iron to the printed circuit board only. Temperature of the iron tip should not exceed 350°C. Soldering time should not exceed 3 seconds. 

- Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. 

- Please contact our Sales office when your application are considered the following: 

The device’s failure or malfunction may directly endanger human life (e.g. application for automobile/aircraft/medical/nuclear power devices, etc.)
