Common Mode Filters
For High-speed Differential Signal Line / General Signal Line
ACM Series ACM2012, 2520
FEATURES
• Although greatly miniaturized, this wire-wound chip-type filter
maintains the characteristics needed for a common mode filter.
Common mode impedance is 1000 [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.
