Common Mode Choke Coils for Signal Line SMD
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.
