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.
