Re: Smoothing capacitor value ?
OK, so what is the circuit? Simple PSU with bridge and smoothing cap with tappings on mains TX or resistive dropping and unregulated or with adjustable regulation or regulation and active smoothing?
A basic non regulated will need between 4700uf and 10,000uf, suitably rated cap for no load, minimum of 25v, 35v advised.
