Power Supply Capacitor

[Boyan Silyavski]

A piece of advice about capacitors:

Don't buy a capacitor from non reputable seller, especially ebay. Too many reasons to explain here but in short : China, not genuine, quality, NOS etc.


Buy from Mouser or RS online, i don't know about Rapid online, but i assume as Clive pointed you there it should be good. Buy a brand capacitor- Panasonic,etc. Look for rating 85C or even better 105C rated


Plus i wouldn't save a dollar from a capacitor. A good normal one 85C is rated 2000-3000h at the temperature rating. A better one exact value, not a stack of cheaper smaller ones, that is meant especially for computer and other power supplies could be rated 105C and 20 000h . So its up to you if you will save a $ or 2 from your power supply. Questions to ask yourself: how many hours per day the machine will work, how many years you expect it to last, do you have time later to stop production and investigate eventual problems.

If it was me i would buy a single screw terminal can type capacitor, meant to be there, less space, easy to exchange.
