APACITORS
These MLC capacitors are specially designed to lower
inductance by altering the aspect ratio of the termination
in conjunction with improved conductivity of the electrodes.
This inherent low ESL and ESR design improves the
capacitor circuit performance by lowering the current
change noise pulse and voltage drop. The system will
benefit by lower power consumption, increased efficiency,
and higher operating speeds.
