When should I use a low ESR capacitor
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). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed …
