3-terminal Filters
For Power Line
ACH Series ACH3218, ACH4518
FEATURES
• The ACH 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 ACH 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 preheat-
ing 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 cir-
cuit board only. Temperature of the iron tip should not exceed
350°C. Soldering time should not exceed 3 seconds.
