Overview of ALC2012-900-2P-T00
FEATURES
• Downsized wound type chip common mode filter that
maintains required common mode filter characteristics.
• Impedance for common mode noise can clear 65Ω [100MHz],
and has excellent EMC suppression.
• Differential mode impedance is suppressed, so there is virtually
no affect on high speed signals.
• Conforms to the RoHS Directive.
