My option of them is BITT - Belong In The Trash.

Unfortunately, I can't buy only Hitano, Nichicon, Rubycon and Fujicon.
They are not only expensive, but difficult to find. Some dirt cheap crap board doesn't worth the effort and the shipping price.
I'm sure that all of these are generic "brands" I've tested some of the capacitors. They behave a bit a little better than a Capxon or Sus'con.

Re: What is your opinion about this brands of capacitors?

Teapo is the only one worth looking out for, out of all those brands.

Right after it, OST would be an OK choice.
Then Daewoo... but it would really depend on the series and the specifications.

Considering Teapo is bundled with those other generic unknown chinese brands, it wouldn't surprise me if they'd be fake.

televizora,

You can buy genuine components from Farnell : http://bg.farnell.com/

RS-Components should also be able to help you : http://export.rsdelivers.com/

You can probably also order components from TME.eu , I think deliver all over Europe : http://www.tme.eu/bg/

I've ordered from all three and they store genuine components and the shipping costs are very reasonable.

I hate teapo seen loads of the rebadged Gluxon ones fail on Vestel psus they are junk.

Re: What is your opinion about this brands of capacitors?

...

Ok, what about Nichicon, Sancon, Fujicon and Sanwa? I found a cheap supplier of Nichicon. I have to notice that I have built up this pile of capacitors over a period of several years.
It was interesting for me to check if someone ever heard this Chinese brands of capacitors. Or only here, they are selling this trash in our local stores. I found a supplier of capacitors, but he only offers Nichicon, Sancon and Sanwa. I think that Nichicon is the best from the three listed.
I already knew the online stores you mentioned. But I don't really like to deal with electronic payments, because I still don't have a bank card registered for electronic transactions/payments.
I like Hitano, but in the only place, where I can find this capacitors, the prices continue to grow, and I really don't like this. These are nice capacitors, but I'm not willing to pay 0.5$-1$ for one piece rated at 25V

Re: What is your opinion about this brands of capacitors?

Nichicon is a top quality brand of capacitors.
But if the local market is so crap, it's most likely those Nichicon capacitors are counterfeit (fake).
Samwha is a relatively known brand of capacitors, it is used a lot in lcd monitor power supplies, and you'll find lots of pictures of these capacitors going bad inside lcd monitors. Could be they're bad quality, could be the lcd monitors have bad ventilation so they die due to overheating... point is they're not great. I'd class them below Teapo, maybe on par with OST.
Fujicon and Sanwha with n .. chinese crap.

Make an effort and get a card that works with electronic transactions. I have a basic Visa Electron card from ING and it works just fine.

Nichicon , Rubycon, United Chemi Con, Panasonic are top brands of capacitors. Most of the Samxon series of capacitors are good.. Taicon is a good manufacturer buy it's hard to source from distributors.

If less choice, Teapo (from a known distributor, not local market) will do.
Ltec is another taiwanese manufacturer that is used a lot by Delta which is a very good oem manufacturer of power supplies, and they're generally good.

TME.eu stocks Samwha, if you have no choice, they will work.
They also have Aishi capacitors, which are often used in computer power supplies and all kinds of lightning equipment, so they're not terrible, but they're also not great. Pretty much on par or maybe even better than Samwha.
For general purpose applications (linear regulators, simple circuits, not switching power supplies or very low esr) I'd use Yageo and/or Jamicon. I wouldn't use them in circuits where there's need for very low esr.

TME.eu also stocks Elite brand capacitors - these were also used a lot in lcd monitor power supplies, even in some regular computer power supplies... seen quite a few die, so definitely not to the level of Japanese brand name capacitors or even taiwanese capacitors.

Farnell also stocks Vishay and cornell dublier and illinois capacitors and Wurth Electronics - wurth is a relatively new player on the market, they're just recently distributed by Farnell but a lot of people making designs trust the brand, they say they make and sell good components. These brands are very good but less popular and expensive (except wurth) and what's stocked at distributors is often not very suited for computer repairs. Epcos is in the same category, good but don't really see it in regular computers and consumer switching power supplies.

Wurth is almost certainly a re-brander of Taiwanese capacitors.

As such, their polymer line is probably ok, but their electrolytic line has the same level of reliability as Lelon.

Don't mean to be needlessly disputatious, but lots of respected manufacturers use Lelon on their PCBs, that doesn't make Lelon a good brand.

I'm sure you also have such a problems, because you are practically my neighbor. I didn't mean that everything in the local market is fake or bad, just what I have in my proximity.
The biggest problem in front of me is that a it's not economically justified to buy small quantities. I can't just order 5 or 10 capacitors and pay 10 times more(than the price of the capacitors) for the delivery of each order I make.
We have one local manufacturer of capacitors (EA, KEA brands) and I'm wondering whether to try these. The ones from the communist time with this particular brand weren't so bad. This is the Bulgarian brand - http://www.conis-bg.com/EN/availability.php
By the way, do you think that this is counterfeiter capacitor? Some Bulgarian store. I set the language to english, do not worry

Re: What is your opinion about this brands of capacitors?

I'm sure you also have such a problems, because you are practically my neighbor. I didn't mean that everything in the local market is fake or bad, just what I have in my proximity.

Once every 6 months or so, i buy 50-100 pcs of the most common capacitors used in computer and monitor power supplies from stores like Digikey in US, or Farnell in UK. For some, i buy even bigger quantities.
Shipping is free for big orders, these days I think at least $200 to get free shipping from Digikey. Digikey has smaller prices when buying in volume compared to the European stores, but when package arrives in country, you have to pay a few percent of customs taxes and the VAT if you don't buy them on company account but even with these added costs, for some components you get better deal compared to buying from farnell or tme or rs-components.

I also plan ahead and make lists of less often used parts like fuses, commonly used mosfets, igbt ics, leds that may be used to fix led monitor backlights, zener diodes (you can use zener diodes in place of leds in led backlights ) etc,, that I may have to buy locally and when I need something i can't trust to buy locally, I place an order on Farnell or TME.eu for that part, plus some of the parts that I need less often so that the fixed shipping cost for a tme.eu or farnell order would not hurt my pocket that much. I don't order just 1-2 components at a time.

In my local town, I'm aware of only one small "mom and pop" style shop that sells electronic components but these guys also order from various distributors.
From time to time I had to buy some weird resistors for example, and at the end of my order they simply reused one of the TME.eu bags they got other parts in.
They don't even deny ordering from these bigger distributors... they just buy in hundreds of units to get better prices and add profits and can keep the parts for months on shelves and they'll eventually sell.

And one more thing ... when i'm getting close to making another huge order, after 6-8 months (sometimes even sooner) and I plan on making another big order, I sometimes start listing whatever old capacitors I still have on eBay and try to sell packages of 5 or 10pcs of that old stock for almost no profit at all. Just enough to cover the envelope costs and postage and the eBay fees and maybe less than half a dollar in profits. I get rid of old capacitors and can use the money i get for the next big order.

It makes it easier on my pocket because I get some money back, and I'm getting a lot of positive feedback on the eBay account, which I may use in the future to sell more stuff at better margins. It's a win-win.

By the way, do you think that this is counterfeiter capacitor?

Nichicon is one of the brands that's most generic. They have the classic + vent on top which is used by lots of brands, unlike Rubycon or Teapo for example which use custom vent patterns.
One of the ways you could tell if the capacitor is counterfeit or not is by checking the quality of the printing on the label and how the material in the bung (the rubbery bottom) feels and how it's patterned. For some smaller capacitors, the bung is basic shape, for bigger capacitors the bung has a specific shape with channels to allow solder to flow up on the leads and for other things. A lot of fake capacitors usually don't bother using these mode complex bottoms.
As for print quality... really, what could you say from a tiny picture? It's also the worst angle possible where I only see the brand "nichicon" and 47uF 200v ... i don't see the series (the 2-3 digits), the temperature rating, the production code (usually 4 digits, year and week of manufacture).
And nowhere on the page is it written the SERIES of the capacitor. Nichicon makes probably close to 100 series of capacitors, maybe even more.. you can't just take out a capacitor from a circuit and replace it with whatever else fits there, the new capacitor has to match specifications like ESR values, ripple current etc.
I'm also looking at Digikey and Farnell for any Nichicon 47uF 200v capacitor with 4mm pitch between leads and 13x20 mm in size and there isn't any.

5mm is a common pitch between leads and if that's the actual distance between leads, you end up with just a few series : http://www.digikey.com/short/35tm1r

Some series are brown (cs, cy, ps,pw) some are black or dark green (vr), the rest are green. None are 13mm x 20mm , but there's quite a few that are 12.5mm in diameter.. So if that one is genuine, it's probably Nichicon VZ at 12.5x22mm or maybe Nichicon VR , or VZ or VY .. here's a shorter list : http://www.digikey.com/short/35thc5

So as you can see the specifications on that web page don't match with anything Nichicon sells.. maybe they're lazy or rounded up the specifications.. but could just as well be a fake capacitor.
