OK, great, thanks for that correction, Adam! We need to get that info incorporated into the Flexmod instructions for the non-engineers like myself.

It's designed to smooth out any voltage drop if your power supply can't keep up with the load.
Andrew explained it at the NWLEM. He was thinking about the funny spikes I observed on my flexmods when running them at high currents. He theorized that part of the problem may have been a momentary dip in the supply voltage. That would explain the spikes, both positive and negative. I just got a new oscilloscope, so I hope to replicate my tests this weekend to see if the capacitor helps.
But just to reiterate: that cap does not go across the output of the Flexmod! It's designed to be installed on the power input side only. And it has nothing to do with the lead lengths from the flexmod to the diode at all.
