Re: Help me
The KZE's are not original but the original caps were in the same location. There is actually nothing below them just a few near by resistors, the originals were leaking hence the replacements.
I know the unit uses at least 24V AC where the power is distributed is beyond me. I will check out all the suggestions thanks for the assist....

Re: Help me
As promised here is the pic of the entire board
jsog the caps have no other markings except for what I have already posted and the temperature rating which is -40+105 C. I checked each one and nada...Leave a comment:

Re: Help me
PCBONEZ and jsog
Thanks for the info. I will try to get a full shot of the circuit board but I'm at work at the moment.
The item in question is a touch screen thermostat, sorry PC you guessed wrong
. Two of the five caps are side by side and in a cramped spot so a 8mm will not even fit but the others have a little wiggle room.. Stay tuned for the pics when I get home in the morning.

Re: Help me
I thought when replacing a electrolytic with a polymers that the specs would have to be different on the polymer? also this is not for a motherboard so would a polymer even work?...Leave a comment:

Yes I'm in FL. Digikey and Mouser have noting in that size (dimension) I will check the other links you provided. Thanks...Leave a comment:

Three of them maybe, but the other two definitely not....Leave a comment:

Are these bad or just installed poorly installed.
I'm speaking of the small black Ketuo 6.3v 470uf caps. this small thermostat has 5 of them
and they are all slightly leaning. The larger caps in the background were just replaced due to leakage.
On another note I'm having a hard time tracking down ones of the same physical size to
replace them with just in case they are failing. I checked digikey and Mouser with no luck.
They seem to be around 6mm in width and 8mm tall but due to the confined space I think
10 mm is the tallest that will fit.
The closest I have found...Last edited by v b chil-n; 08-16-2011, 01:12 PM. -

Re: Poly Brands
Yes I know that is why I said I could not locate the part # for the UCC to make a direct comparison. He is going on the half capacitance rule with a high ripple current and low ESR. I just noticed that the UCC are PSC series so the specs on the Nichicons seem a bit better, 6.3A ripple vs 6.1A for the UCC and 5.0 mOhm vs 7.0 mOhm for the ESR all other specs are the same....Leave a comment:

Re: Poly Brands
Thanks, I only ask because Nichicon has 6 different series listed on digikey and I didn't see a part # for the UCC on Badcaps for a direct comparison.Leave a comment:

Poly Brands
I'm looking at ordering some caps from Digi-key for a busted thermostat and offered to get some poly's for a friend of mine. Are the nichicon poly caps as good as the United chemi cons offered here?

Re: Xunda caps, what is a good replacement
Thank you for the recommendation, I have narrowed my choice to Panasonic EEU-FM1H331L and the Chemi-Con EKZE500ELL331MJ25S. which of the two is the better cap?...Leave a comment:

Xunda caps, what is a good replacement
specs are
Xunda TM series 330uf 50v 10x20mm ripple current 1460mA @105 deg impedance 0.050.
I'm thinking of digikey mouser as a source so far digikey is my preference.
