content: Hi, I recently made a website for seeing the quality of capacitors and thought some of you guys would be interested.I put a HUGE list together rating capacitors and giving a popular application of the capacitors. I made the site myself and wrote it in html; and I am running it on my own server just for the fun of it. I tried my best to make it look modern and a site you would want to look at and something you would want to go back to because it looks good overall.I also would appreciate if you guys can shoot me an email (address on site) or on the forum on what I should change to make it better; add a brand or change a rating, I want this site something to reference and something you'll all like.. I hope you enjoy, it took a while.Oh and the sitehttp://capacitorlist.comInfo for the server Nerds:Ubuntu 16.04(Apache)IBM M3 x3650(virtualized esxi)48GB of ram (using 12 for the site)(I know its overkill)2 of 8 cores of XeonsEnterprise Minuteman UPSDell Switch and Custom Router

content: If I introduce a new line of SevenCap(R), how much do I have to pay to get 10/10 ratings on here?Just teasing. But, as a professional, just at a glance, it doesn't strike me as anything peer-reviewed or anything. Are these reviews based on consumer sightings? CM purchasing? Do they match their datasheet specs? How's their supply chain look like? Can you get me ten thousand by tomorrow?...I mean, if it's based on consumer sightings, then those results depend on how they're used in circuit; I can drop a Nichicon into a badly designed circuit and have it last shorter than a Capxon. Conversely, I have a few things I know contain Capxons, which are many years old and still running just fine (they were obviously chosen appropriately; and perhaps some luck of the draw, since single digits is hardly a representative sample).And speaking of stats, if these are based on sightings, then how many went into them?There's an awful lot of information missing, to make this anymore than a popularity contest, is all I'm saying...Tim

content: Quote from: T3sl4co1l on October 20, 2016, 04:11:50 amThe way the capacitors are rated is based on consumer sightings in the reliability in electronic goods, although mostly consumer goods(switchmode psu's, motherboards or system mainboards). The ratings behind capacitors is supposed to give the average Joe, or a experienced tech to look at a capacitor, and determine if it follows a history of being a reliable or unreliable component, and know if it should be changed or if a product seeks for high quality components.Many companies in Taiwan may make a Rudycon or a cap that sounds like a good brand, then with the table one can see that the cap is a fake of a good brand and that it most likely follows a manufacturing process that can care less about quality control, not caring about deceiving people who may not know the difference. Then based off that it would receive a poor rating and be categorized as low quality.Thanks for you great response,Robert

content: Wow... what a crap website.Lots of typos. Nichecon in some place... even the title of the page has a type , it says Capasitorlist.com .. are you 12 and not capable of running a text through a spell checker?To put Taicon and Teapo in the same place with some crap brands , with a score of 7... Taicon is heavily used by brands like Delta which are high end power supply OEMs... Teapo is huge, used in lots of power supplies, nowadays is very close to the quality levels of Japanese manufacturers like NichiconSamwha is heavily used in Samsung monitors.. it's not great but considering the huge amount of products they're used in the don't deserve a 5 Su'scon was heavily used in LG and other monitors and again it's a relatively decent brand ... i can certainly rate them higher than 2.5, especially higher than brands like capxonLots of brands like Obbligato or Rel-Cap are probably capacitors custom-ordered and printed with another brand for the manufacturer of those audio products.Jensen capacitors rated as 10, above some high end Japanese manufacturers? Based on what... they probably don't even fabricate their own capacitors, probably just printing text on chinese capacitors they custom order.Marcon ... i think this brand is long gone, sold to united chemi con and they previously were owned by toshiba or something like that.

content: Quote from: rdl on October 20, 2016, 04:04:20 pmThanks for the fixes, I am using a software called notepad++ for writing this up and when you spell something one way, it will then suggest the incorrect spelling as an autofill. I suck at spelling and I just noticed the errors once you mentioned them; so thank you. I do appreciate ya for that.-Robert

content: Quote from: mariush on October 20, 2016, 11:37:32 pmUnfortunately I can't run it through a spell checker because it is all html and the software notepad++ does have a built in spell checker. I also do this on my free time from school at night and sometimes just rush it and don't pay attention, so sorry for that. I'm 15 and thats close enough to 12 so yah I guess I'm 12.The rating of 5 is not bad, or good; it's middle of the road. I have a second page that you get to by clicking the "Full Rating Breakdown" button under the reference scale giving a better explanation behind why it was rated at that specific number. The Obligatto and Rel-Cap caps are handmade and are not in some partnership with another company so they do get a high rating for that. The Marcon brand is just there for people who might run across it in the future.

content: Hi RobertCool idea. Unfortunately, I dont think the idea is very useful. Capacitor brand is only 1 factor. The series of capacitor and the circuit it is designed into is just as important!Also, empirical data is important for engineers. Engineering relies on data, not opinion. I dont want this to be discouraging, as your only 15, but I do not think many professional engineers will find this useful. Keep on building things and post some of your projects. I think you will find the community much more accepting.

content: Quote from: iampoor on October 21, 2016, 07:50:13 amYes, it is much more difficult than simply looking at the brand and knowing that capacitor is bad.Some of the lower rated capacitors are probably ok, but have a low rating because they are cheap and are therefore being used in places requiring a capacitor with a high ripple current rating instead of a cheap general purpose one. Therefore they will fail soon.No doubt, there are many bad capacitor brands, but there are also many designers/manufacturers simply using the wrong/cheapest capacitors instead of adequate ones.

content: Quote from: iampoor on October 21, 2016, 07:50:13 amThat's very true, that the circuit design is a big contributing factor also followed by the series. Really the main purpose as in the circuits it's used in is in switch-mode psu's. Simple electronics with low voltage, low ripple under low temps will have no problem running indefinitely under those conditions really with some onehunglow brand caps. But where most electronic appliance psu's fail first is with the caps, with high ripple, high peaks and currents really stressing a cap to then blow after a couple years. What my site aims to do is let someone look at a blown cap, and if it is a low quality, they can find a good alternative brand equivalent to repair whatever device it may be.I know this is not the site to be "advertising" something like this, really an electronics design engineer really just needs to say what goes where; then the manufacturer picks a brand that suits their product. I only am really here for your amazing advice in making the site a reliable source of information for other people where they find themselves fixing something and figuring out what is good or bad part. A site for the amateurs to know the difference between good and bad replacement cap for a psu they might try to fix. Thanks for the advice.

content: I would just like to give a big thanks for the people who critiqued my site and helped make it a much better site than it was before. I also have made some functionality changes added some pages and improved the ascetic just a bit to make it a bit nicer to use.I've gotten to the point of the site being fairly accurate with the information on the ratings of capacitors so any design ideas would be much appreciated to help make the site more pleasing to use. Maybe refine some things here and there.Thanks again,Robert
