What series of capacitors with a voltage of 35V and 50V / 63V is recommended use in switching power supplies?For values as from 1000uF?

Re: Capacitors for SPS
A power supply uses many caps in different roles. A cap used for filtering is not the same as a startup cap for example. Or a cap filtering 20amps is not the same as a cap filtering 500miliamps.
Which role you are talking about? -

I like nichion pw for smps in those volts.Comment

Re: Capacitors for SPS
Sorry, forgot to mention that the capacity of filtering caps also depend on the frequency (on which the switchers are working).
So, it's not too easy to tell a value without knowing some information.
Usually, for 10A a value of 1000uF should be fine with most of the modern switching PS.
And because a PC PS used a 3300uF filtering cap for 30A, I suppose that for 20A you should be fine with a 2200uF.Comment

Hi, my Vizio M60-C3 does not power on. No lights whatsoever. Upon opening up the TV, the power supply board has 4 bulging capacitors. Each is 1000uF 16V. I have read that one can use capacitors of the same uF and higher voltage rating, but is 1000uF 35V capacitor too high of a voltage rating? My local shop only has these higher voltage capacitors so would rather just buy the 35V variety if it is OK to use them.
Any thoughts if OK to use these higher voltage capacitors? -
I just bought some 1000uF 10v capacitors from eBay to fix my Samsung 2220WM, but it seems like they are already bulging? Are they ok to use? Thanks.... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of...
