50V LARGE caps 18x22 max for Power Supply

[Florida-Rob]

Need help please, i need most capacitance as bulk to hold up after the bridge (12-24VAC = 34V peak+) as bulk
max size is 18Dx22L mm

The next best is 1800uF

I see a bunch of SMT and PTH 1500uF
i.e
YAEGO CC0402JRX7R9BB102
YMIN LKMJ2001H182MF

Thoughts ?
is KNSCHA ok ?
spec says its AL foil + Ethanediol

I have space for 2 caps, and need more than 300uF, hence why the 2 x 2200UF appeals
I do have some poly caps aloingside, 2 x 120uF 10x10mm,
NCC HHXC500ARA121MJA0G
Panasonic EEHZC1H121P
Lelon HBW121M1HTR-1010

Why that strange capacitor size of 18x22mm?

[Florida-Rob]

We have a max height of 22mm, other than that, open.
The best capacitance for thr 50V (or greater), seems to be 18x22

[CapLeaker]

What if you relocate the caps?
or use 35V caps?
I mean 24VAC = 34VDC.
what kind of power supply is this? Linear or switcher?

[Florida-Rob]

max height of the box is 22mm, plus tolerence, sp 24mm for the cap
its on a 24VAC rail, so 34V normal, plus curge, so needs to be 50V
it feeds an active bridge, then a buck-boost 4 FET convertor.
Hence think I have found the best I can get, hence need to knwo if this manufacturer is ok ?

Got no Idea if that cap brand is any good. Will it work? Probably. Is it a good quality part? Probably not. Capacitance alone isn’t the key here. The deciding factor is how much the 24VAC transformer can handle as an output. Not much good if you have the biggest caps, but only can use 30% because of the 24VAC transformer supply.

2x 2200uF is a lot more than 300uF
Why not go down in value a bit so the sizing is less restricted, and source something from a known-good brand like Panasonic?

Never heard of KNSCHA, never seen them in anything, it's not even a pronounceable word!
Can't say I'd trust them to last.
