When should I use a low ESR capacitor
Power-supply capacitors smooth ripple on DC power supplied from AC sources. When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor).
Why the Capacitor in Your Power Supply Filter is Too Big
The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a …
