It seems as though FM pannies are pretty much jellybean when it comes to SMPS output filtering caps. Problem is the darn things are very expensive from Mouser plus you have to buy a ton of them to get the price break.
The thing is HE nichicons can be had at almost a quarter of the price at Future Electronics. The kicker is the ripple current rating on the HE's is too low to mach the crap caps specs on most applications. Now if they had HD's it would probably be a good fit but unfortunately they don't carry them.
Can I get away with going up in capacitance to the next size made in the same voltage, or should I go up in voltage and keep the capacitance the same to meet or exceed the ripple current ratings of the cap being replaced?
Don't get me wrong I think pannies are great, its just why buy them when you can get three caps that will work in a pinch for the price of one?
