Dingfeng Capacitor-----Filter Capacitor
Filter capacitors are capacitors used for filtering of undesirable frequencies. They are common in electrical and electronic equipment, and cover a number of applications, such as:
Glitch removal on Direct current (DC) power rails
Radio frequency interference (RFI) removal for signal or power lines entering or leaving equipment
Capacitors used after a voltage regulator to further smooth dc power supplies
Capacitors used in audio, intermediate frequency (IF) or radio frequency (RF) frequency filters (e.g. low pass, high pass, notch, etc.)
Arc suppression, such as across the contact breaker or 'points' in a spark-ignition engine
Filter capacitors are not the same as reservoir capacitors, the tasks the two perform are different, albeit related.
