Input filter capacitor replacement 560uF

[chud]

Hi,
I am recapping my fanless Thermaltake 350W PSU and am having some trouble with replacement of 2 x input filter capacitors. (have recapped rest of it with mostly Panasonic FM)

The original ones are 200v 560uF TEAPO ones 25mm wide, 30mm high and 10mm hole spacing.

I was intending to replace with these, (same size except 40mm high) ;

PANASONIC - EETED2E561CA - CAPACITOR, 560uF, 250V -
AC Ripple 2.14A, ESR 266 - problem is Farnell are out of stock for months (UK).

only other thing I could find are;

PANASONIC - EETHC2E681CA - CAPACITOR, 680uF, 250V - these are in stock in Farnell, the ESR is LOWER at 244, but the AC ripple is also LOWER at 1.7A

Could anyone advise if these would be suitable, I am worried as the uF rating is about 20% higher but I admit to not knowing enough to make a judgement on if this is ok or not? (I cant seem to find any 200v 560uF ones anyway)

Any help much appreciated!
Thanks
Rich

Re: Input filter capacitor replacement 560uF

ripple is the important thing on the input.
can you get a bigger one - 680uf maybe?

Re: Input filter capacitor replacement 560uF

THIS looks like it could fit the bill (AV ripple rated at 2.77A). A bit of extra primary filtering can't hurt Not to mention they still have a few in UK stock.

Alternately, THIS could work as well ("just" 2.5A ripple in the specs). These seem to be in stock as well.

Not to mention they're both cheaper than the EETHC2E681CA you mentioned

Re: Input filter capacitor replacement 560uF

Khron, thanks for your reply, unfortunately they are both 85C ones and as the PSU is fanless it gets somewhat hot under normal operation, so feel they should really be 105C ones (and one of them is almost butt-up against one of the heatsinks. Do you know if 680uF ones are acceptable replacements for 560uF? Thanks for any advice.

Re: Input filter capacitor replacement 560uF

If 105C is a must, then i seem to have found THIS as a suitable replacement. 1.7A ripple, but i doubt that's too big a concern on the primary smoothing side.

Re: Input filter capacitor replacement 560uF

when your smoothing the mains, a higher uf is better - as long as you have space to fit it.
i'v seen cheap junk use 330uf and some high end stuff use 820 or higher.

Re: Input filter capacitor replacement 560uF

stj: ok thanks for that, I guess ill go for 680uF then - will need to Dremel abit of heatsink fin off, the existing Teapo are 30mm high, I think there is about 35mm of space, and everything I can find is 40mm high. The width has no room to manouver and is 25mm.

BTW my PSU is the Passive PFC version (W0050 ) of this review "Thermaltake Silent PurePower 350W Fanless Power Supply" - ;

There are lots of pics at end of the review - mine has a primary transformer part where there is empty space in this reviewed one, in the rear corner behind the copper fins.

Re: Input filter capacitor replacement 560uF

seems Farnell don't have anything in the ''TSED'' Series (high ripple) less than 1000uF @ 200v in stock.

So I am proposing to get the EETED2D102CA's
http://uk.farnell.com/panasonic/eete...t=EETED2D102CA


Voltage Rating:200V dc
Effective Series Resistance:149mohm
Series:TSED
Height:45mm
Outside Diameter:25mm
Capacitor Case Style:Radial
Mounting Type:Snap-In
Lead Spacing:10mm
Operating Temperature Range:-40°C to +105°C
SVHC:No SVHC
AC Ripple Current:2.84A
AC Ripple Current @ 120Hz:2.84A

Could anyone say stop if this is going to cause a problem ( I appreciate its going to involve more Dremel action due to huge height) ? many thanks

Re: Input filter capacitor replacement 560uF

Unless Farnell is a requirement, I think this would be what you are looking for.

Re: Input filter capacitor replacement 560uF

i also use rapid for parts.

Re: Input filter capacitor replacement 560uF

softTest: thanks but shipping is £12 extra! Farnell is free shipping (and I allready ordered what is out of stock, before finding out its going to be months before they have any, so easiest to just change it)

stj: they only seem to sell SAMWHA caps which I thought were proper badcaps ?

Re: Input filter capacitor replacement 560uF

i'v not had problems with big mains smoothers.
they arent suitable for high frequency stuff - so they shouldnt even be mentioned normally.

Re: Input filter capacitor replacement 560uF

do yourself a favor in the future, screw fanless. fanless is just asking for trouble. a good deal of them are pretty crappy too.

oh, and change your location setting in the user cp, it was not obvious that you are a brit until your last post

Re: Input filter capacitor replacement 560uF

Why screw fanless? Some people like a quiet PC even if it comes at the cost of a recap or PSU replacement every few years.

It's a tradeoff. Silence is golden for some.

Re: Input filter capacitor replacement 560uF

I completely agree that silence is a great desire for some people.
I really like a quiet PC and do appreciate and enjoy the benefits of quiet PC's.

Having said this, my PC's are not that incredibly quiet. However they are not as loud as some of friends PC's. I live with a bit of noise and use headphones a fair bit.

Re: Input filter capacitor replacement 560uF

i couldnt take a quiet pc, i'd be constantly checking it was on!

i love my Hovercraft - 3 x 120mm 84cfm fans on the front blasting air over the drives & mobo 24/7
it's the woooooshing sound of reliability!

Re: Input filter capacitor replacement 560uF

hey id like to know a good replacement for a 560uf-4v cap?.... i have found very hard to find those.... is for a p4sd mobo.

thanks

If there's a display on the monitor and it's accepting the characters you type, it's on!
The last stock PC I had was back in 2000, everything since custom cooled and passive if possible (and if fan forced the quietest available).
I'm amazed at the stock system screamers I hear at other peoples houses. They are so bad I couldn't live with them myself. My PC is on 24/7, I work on it, watch vids on it, and relax in front of it. I don't want no screaming 60mm fan in it, most things are 120mm and flow the same air as those 60/80mm fans and are low noise 120mm fans.
The loudest thing on my PC is when I put a disc in the ODD
