Directionality Explained

heaudio123,

I am intending to use about 33,000uF and up, depending on price and low frequency ripple current.  Among the 105 degree caps, there are quite a few choices.  What brand is usually the best ?  Nichicon had a great reputation, is it still the same ?

Thanks

I assume at 50-63V. You won't get 105C/10K hours in those values unless you build it from a bunch of smaller ones. You may find one, but very expensive. There are 8,000 hours at 105C and that is likely close enough.  Nichicon, UCC (United Chemicon), Kemet, TDK, Cornell all have stuff up in that size area and all reputable.  The high temp, long life are typically high ripple/low ESR as well. Most caps in audio I have found are 85C/2000 hours.  Keep in mind even though they are 105C/10K hours, pretty much all bets are off once you get to about 15-20 years.

I would even trust many of the Asian brands if I knew I was getting the real thing, but unless you are buying from an authorized distributor (Arrow, Mouser, Digikey, Future, Avnet, Mouser ... etc.) you are taking your chances.

Grades are based on how well the student memorizes whatever is in the book, right, or wrong

what ????
I guess maybe only when you are studying some brain washing courses  filled with leftist dogmas and worn out slogans that you have to memorize in order to become some kind of commisar or a SJW blogger or some other non contributing to society moron...
Not in engineering...that is why you don't see many engineers in politics...they can think and solve problems...

You are not that knowledgeable. I like teaching you. A lighter made in heaven.
