How do you specify "high frequency" in terms that capacitor
manufacturers use?   For example, I don't think it's one of the filter
boxes on Digikey's selection tool for capacitors.

Tom Lee suggests using four 1uF 50V (or higher V)  ceramic capacitors
in parallel in place of C1.  It makes a lot of sense.
