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.
