Common Mode Filters(SMD)

Conformity to RoHS Directive

For High-speed Differential Signal Line / General Signal Line

ACM Series ACM2012, 2520, 3225, 4532 Types

FEATURES

• Although greatly miniaturized, this wire-wound chip-type filter

maintains the characteristics needed for a common-mode filter.
Common-mode impedance is 1000Ω [at 100MHz], so this filter is
greatly effective in supporting noise.

• Almost no affect upon even high speed signals since differential
mode impedance is kept low.

• This series includes both 2-line and 3-line types. They are used
for various types of circuits and noise.

APPLICATIONS

• Used for radiation noise suppression for any electronic devices.

• Used to counter common-mode noise affecting signals within
high speed lines.

• USB line for personal computers and peripheral equipment.

• IEEE1394 line for personal computers, DVC, STB, etc.

• LVDS, panel link line for liquid crystal display panels.
