or

this one is on sale for $0.265

you don't get capacitors for a particular brand of power supply.

It varies from model to model of power supply and who makes the power supply and what capacitors they used that week.

In general, both capacitor series you linked are good, but not really suitable for power supplies, they're a bit on the low side of the specs.

16V 1000uF Rubycon "YXF" 10x20mm 1050 0.078 26 cents
16V 1000uF Panasonic "FC" 10x20mm 1220 0.052 92 cents

--OR--
16V 1000uF UCC "KZE" 10x20mm 1820 0.023 25 cents
If you use this cap in a pi filter, make sure the input cap/s' ESR matches that of the output. For this reason, I wouldn't recommend the Nichicon HM 16V 1000 which are only like 18 cents for some reason, but have a ripple rating of 2550.

thanks mariushm,

there are about five swallon 1000uF 16v 105°C 20x10mm on the psu board.
Thinking to have them replace, but there are lots on selection.
When you say they are on the low side, do you mean the Ripple
Current?

[belippy]

hi mockingbird, so in that case for my psu. Is it better to use a higher amp ripple current of lower?

Thanks,
belippy

how about this one:.

16V 1000uF Panasonic "FR" 10x20mm 2108 0.020 67 cents

The ESR value is low for YXF, it's not a series designed for very low esr. 0.07 is relatively much.

Ok, knowing the diameter helps, I was concerned you might have 8mm capacitors which are hard to find.

You need capacitors with high ripple and low esr/impedance.

These will do (the list is more or less from best to less good, but all better than what you initially selected) :

Rubycon ZLJ 1000uF @ 25v 10mmx20mm 2500mA ripple, 0.028 ohm http://canada.newark.com/rubycon/25z...0uf/dp/84R1034

Panasonic FR 1000uF @ 25v 10mm x 25mm : 2470mA ripple, 0.018 ohm impedance http://canada.newark.com/panasonic/e...r%20Capacitors

Rubycon ZLH 1000uF @ 25v 10mm x 23mm : 2250mA ripple 0.018 ohm http://canada.newark.com/rubycon/25z...25v/dp/39T8696

Using capacitors rated for higher voltage is safe, no worries about it. The ones rated for higher voltage are usually also larger in diameter, but in this case there are plenty of capacitors with 10mm diameter and 25v rating which have great specs for you, so if you can fit slightly taller ones these above are great. The Panasonic FRs are only 5mm taller, the ZLH are only 3 mm taller, which I'm almost sure you won't have any problems with.


Panasonic FM 1000uF @ 16v 10x20 2180mA 0.019 ohm http://canada.newark.com/panasonic/e...16v/dp/04M9010

These will also work and have higher ripple/esr than what you selected, but I don't have time to look up the ripple and impedance in the datasheet for each of these:

panasonic fr 1000@25v 10x20 (smaller than the one above, slightly lower specs than that one) http://canada.newark.com/panasonic/e...0uf/dp/58T1750

rubycon flj 1000@16v 10x16 (like above, but smaller height) : http://canada.newark.com/rubycon/16z...0uf/dp/84R0897

panasonic fr 1000@16v 10x16 http://canada.newark.com/panasonic/e...16v/dp/74R3415

from this point, ripple is a bit low for psu capacitors but esr is still very good

rubycon zlh 1000@16v 8x20 http://canada.newark.com/rubycon/16z...16v/dp/39K1347

fr 1000@16 8x20 http://canada.newark.com/panasonic/e...16v/dp/74R3416

rubycon zlh 1000@16v 10x16 http://canada.newark.com/rubycon/16z...16v/dp/39T8572

Belippy - You mentioned you're in Canada.. Their shipping is $8 + tax, just so you know... I only order from them $100 at a time, to offset the shipping.

Now regarding what to replace them with... If you want to be safe, post the cap brand and series and then we know what to replace them with.

Watch out for some of the Rubycons... Most of the time, Newark will only sell you 1000 at a time.

The brand is CapXon the top one is 2200uF 6.3v lower one is 1000uF 16v

[mariushm]

the 1000uF selection i made remains valid.

for 2200uF 6.3v you have this

if the capxon is 8mm diameter:

for 10mm diameter:

--anything-- posted here is better than Capxon KF series... Low on ripple, borderline low-esr caps.

thank you guys, I'm
