(1/4) Conformity to RoHS Directive 3-terminal Filters(SMD) For Signal Line 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. PRODUCT IDENTIFICATION HANDLING AND PRECAUTIONS ACF 321825 - 223 - T D Before soldering, be sure to preheat components. The preheat- (1) (2) (3) (4) (5) ing temperature should be set so that the temperature difference between the solder temperature and product temperature does (1) Series name not exceed 150C. (2) Dimensions After mounting components onto the printed circuit board, do not (3) Type apply stress through board bending or mishandling. (4) Packaging style The inductance value may change due to magnetic saturation if (5) TDK internal code the current exceeds the rated maximum. Do not expose the inductors to stray magnetic fields. TEMPERATURE RANGES Avoid static electricity discharge during handling. Operating/Storage 25 to +85C When hand soldering, apply the soldering iron to the printed cir- cuit board only. Temperature of the iron tip should not exceed PACKAGING STYLE AND QUANTITIES 350C. Soldering time should not exceed 3 seconds. Packaging style Quantity Taping 1000 pieces/reel 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.
