Hi,
I was about to order a BOM for a linear power supply for a tube mic and saw that some of the electrolytics I was going to order were out of stock. I searched for an alternative part and before I knew it I had embarked on a journey of selecting what may, or may not, be upgrades for all of the electrolytic caps in the PSU.
I found caps with the same form factor, capacitance, and voltage ratings that had much longer life spans and much higher ripple current capacity.
I am writing to ask: Is there anything I am missing that I should know about? I saw that brands like Nichicon and Panasonic had many choices of caps with similar form factor and the prices were very similar. I went to both companies websites and found they had short descriptions of their different series of caps. Sometimes the prices reflected the longer life expectancy and higher ripple current capacity but sometimes I found no price difference.
I also noticed there were some described as extremely low ESR which as far as I can gather are primarily for switching power supply designs.
Is there anything I may be missing, or I should be aware of, or is it ok to "upgrade", if you will, to the "high reliability - low ESR" grade of caps if you don't mind spending just a bit more money?
Thanks.
