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

not exceed 150C.
(2) Dimensions
After mounting components onto the printed circuit board, do not

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
