Re: List of Bad Cap Manufacturers
Was taking apart an old battery operated radio/lantern to fit a custom rechargeable battery pack in it, and couldn't help but chuckle at the brand of one of the capacitors, I feel like it's trying to insult me.

Re: List of Bad Cap Manufacturers
Well, I just checked my salvaged capacitor collection and found a Rukycon capacitor. What initially tipped me off was the absence of a vent, then the wierd negative stripe (regular Rubycon shown for comparison). Real Rubycon shown is 5x11, but the Rukycon is a 5 or 7mm that they just threw the standard 105°C label on.
Measures 222uF with .88 ohms of resistance. Not sure if that's good or bad.

Re: List of Bad Cap Manufacturers
Do we add (possibly) defunct/bought out manufacturers that made capacitors in the 1970s or earlier?
Like Aerovox ... does not appear to be in business anymore, and 50 years later these capacitors are probably bad.
I just pulled a few "Cerco" branded caps that had really high ESR, IMHO even for "general purpose". Their capacitance weren't too far off and their leakage isn't all too horrible.Comment

Re: List of Bad Cap Manufacturers
I had some Marcon made Illinois Caps and Nichicons (from around the 90s or so) that started leaking down their negative legs in storage, as the legs were starting to turn green and slimy near the bung. The Nichicon caps were mostly from the PL series, and were all never installed.I'm not a expert, I'm just doing my best.Comment

Re: List of Bad Cap Manufacturers
Nichicon PL and especially the PR series were notoriously known for doing this.
I have a number of old Astec PSUs that use these (well, the PL series). But they still seem fine and the PSUs work. Being a don't fix it if it ain't broke type of guy, I haven't opted to replace those caps yet. Sooner or later though, I'll probably run into that issue, I'm sure.Comment

Re: List of Bad Cap Manufacturers
And to think some people say Cheng/Chang/Chong+/-X is "decent"
...
- OK, but which one is the genuine brand one among all of these impostures?
(Hint: it's a trick question... a very very trick question )

That said, I really have no idea which one I'd pick. Probably would have to put a bunch of papers with their names in a hat and draw one randomly. I'm sure the chance of any of these lasting any reasonable amount of time will be just about as random as my hat lottery.

Re: List of Bad Cap Manufacturers
I would pick Chang. All of the others are copycats of Chang (and also copycats of themselves). That being said, the quality of Chang capacitors isn't too good either.Comment

Re: List of Bad Cap Manufacturers
Is that Changxin logo made of mutilated Comic Sans?
Of course, the best is Chongx VEHT. Those turn into Black Cats if you apply their rated voltage.Comment

Are there good brands for 'run capacitors' or 'start capacitors' that are used on electric motors or heat pump compressors? ... r are the good capacitor brands for electronics (power supplies, laptops, motherboards, etc.) also the good brands for run capacitors?
Yeah I know this might be a novice question, but I just wanted to be sure. I did do a search on the forum but did not see this question asked before.

The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts... -
This is a list of compatible laptop motherboard information that I have been collecting for some time.
And it's still ongoing.
Every time I come across information that a board is compatible with another, I write it down.
Anyone who wants to, can continue to expand the list.
Packed in the rar, is an excel table that has additional information.

This is not a definitive list, and I do not claim if it is 100% accurate so please do your own research, based on the information from littlefuse, RS, Farnell and a few other places, using information about the markings on the fuses
Please feel free to distribute, amend, correct, etc... -
