Although most EDLCs are powerful when compared with batteries, they are quite sluggish when compared with conventional capacitors. The typically RC time-constant for a EDLC is ∼1 s, far too long for it to be useful for the common application of 120 Hz filtering (8.3 ms period), which entails smoothing the ripple on dc voltage busses found in most line-powered … - Download [PDF]
