what is the best 47uf 400v-450v capacitor

Not open for further replies.
Stick with caps made for switching supplies from major manufacturers (and sourced from reputable distributors, not EBay). Like pws said, low ESR, low ESL, high temp rating. If you want to waste money on "audiophile" caps, use them in the analog portion where you're unlikely to unintentionally damage something.
Does not matter.
Chokes are best power reservoirs for analog applications.
Foil caps comes second.

For low voltage hi current SS applications chokes and foil caps are unpractical but Black Gates (Elna, Nichicon) do the job well. Low power SS applications mean low current might be treated somewhat similar however not as efficient as hi voltage low current of course.

BTW foil caps and chokes make sense for DC circuits right before analog active components.

Placing them in switching part will cause more efficient RF noise.
Listen :D
I finished the improvement of audio circuit DENON DVD 3910
And came out perfect

Now this second phase of the overall projectl
i planning
To replace the diodes
In the diode bridge to QSPEED diode

I need the best possible capacitor comes after bridge diodes
47UF 400V
Unless you know exactly what you're doing (and are confident that you understand the engineering better than the guy who designed the supply), leave it alone. Switching supplies are very tricky and naive mistakes (like replacing parts willy-nilly) can easily cause explosions.
I do not change the values ​​of the parts
I just replace them with more efficient parts
I just want to treat AC TO DC
Four diodes
Bridge diodes
And capacitor after the bridge

i need cap 47uf 400v
With low ESR
And temperature resistance of 105 C
Well honestly I cannot see any issues with replacing 470mu 450V cap with another 470mu 450V cap once polarity is preserved right. An there is a fuse in front of it anyway.

Major question what is the point?

All audio ethereal related tweaks should be implement after switching PSU not in the switching PSU by itself.
