  My previous comment about the FC being high ripple current may or may not be correct or correct in relationship to the Nichicon FW as there are different specs for ripple current at different frequencies and I don't under stand the issue. There are reviews out there, I just posted one.
  
  
  Denied facts are still facts.

    there are different specs for ripple current at different frequencies
    
    For "classic" power supply filter duty, the frequency is 120 Hz, output from a full-wave bridge rectifier at 60 Hz mains or 100 Hz for countries having 50 Hz mains. Perhaps they state different frequencies for use in switch-mode supplies, which operate at high frequencies past the audio range.
    
    Of course a coupling cap is a different matter as it must pass all audio frequencies, but then ripple current makes no sense in that situation.

  I did not recommend a capacitor ripple current. I usually buy the highest I can find at reasonable cost and size.
