Need help with finding good Caps companies

[markitzero]

I am working on a Dell 1704FPVt Monitor that I got from a yard sell for $1US and when I got it home and it failed to start. When I opened it up I found 5 CapXon"cruddy caps" caps popped. I am trying to find the good Cap Companies to replace the cheapo CapXon Caps.


I don't know if this is the section that this type of post goes into.

The repair tech at my work generally uses Nichicon caps and reckons they are pretty good.
I'm sure there are others around though.

I'm a fan of Panasonic caps.

Rubycon, nichicon, Nippon chemicon, panasonic, sanyo, elna are the best. Samxon, exept GF series which is total fail, also is good. Samwha, exept WB series, Jamicon, Hitano should be also satisfactory for monitors, but I would use slightly higher capacitance or voltage for them to be safe (higher value have also higher ripple current). Check datasheets for max ripple current and ESR. Use series that are same or better on max ripple current or use higher capacitance/voltage caps to meet needed ripple spec.

Ones I trust implicitly: Rubycon, Nippon/United Chemicon, Elna, Sanyo OSCON, NEC Proadlizer
Would have to consider the exact type/model: Nichicon, Panasonic, Mallory

it's a really short list for me.

BTW change all caps except biggest high voltage one. They may seem good but not every non bulging cap is good. Low values doesn't bulge usually. Even if they are good now they tend to fail shortly after repair.

Panasonic FR series are among the best caps on the market and they are surprisingly cheap.

Forgot to say, stay away from ebay when buying capacitors. There are more fakes than real stuff, especially if they are expensive brand.

ok now here is another question were to get them? other then ebay because the only place I know that comes to mind is digikey I don't know any other.

Whereabouts are you?
A few of the international ones I can think of are:
Digikey
Element14 (Farnell)
Mouser
RS-Components

I haven't actually checked which brands they carry though.

[TimNJ]

I'd buy from Mouser or Digikey ,but that's just me.

If you want genuine caps, buy them from from reputable distributors (not eBay). Counterfeit caps may even meet the specs of the original caps when new, but will betray you on the long run.

Generally, follow the advice by andtfoot above, but don't fortget to check shipping conditions. Depending on your country, these distributors might charge a lot for small orders. It could happen that a local distributor in your country might have higher component prices, but would be the better alternative for smaller orders due to cheaper shipping.

EDIT: Seeing that you got the thing from yard sell for $1US, your country should be obvious. I am sorry for my brainfart

I will not be able to get the parts until next month but if I get it up and going and if the display is 100% done I will post pics of the display working. I am going to be replacing just the ones that are popped for now and when I can replace the rest later because I am on a very tight budget and fixed income.

Ones I trust implicitly: Rubycon, Nippon/United Chemicon, Elna, Sanyo OSCON, NEC Proadlizer

Those things are a well-known failure point in Toshiba laptops... sitting right underneath the very hot CPU and rated at only 1000hr@105 they don't last very long, and the solution is usually to replace them with an array of tantalums.

if you're deliberately cooking them, that's a design problem and should probably be sufficient cause to fire the engineers responsible. if they're dumb enough to pick low lifetime parts to place near a massive heat source... they're probably going to be making other mistakes of similar magnitude ie using the proadlizer not as intended by also charging and discharging the poor thing excessively.

Personally my favourites are Rubycon

I've seen some popped Jamicon caps before. I don't recall when.

You are going to save <2 bucks? That doesn't make sense to me.

I have seen all big brands to be dead. I also have seen dead jamicons in computer PSU's, IIRC FSP? put general purpose TK series there which, no surprise, popped. Whatever, I would better replace all of them by cheap samxons or others rather than replacing five of them by rubycons and leave old Crapxons there. Even if you choose crappiest from which I listed, without replacing with bigger spec ones, they will work 3+ years, no doubt. At the same time I really doubt that remaining capxons will last more than 1-1,5 years before some of them fails. If they are not already, maybe they just didn't bulge.

I have $1US in cash and about $2US in my bank, I have to wait till the first of the month.
