Capacitors used for suppressing undesirable frequencies are sometimes called filter capacitors. 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
