not exactly. there are 2 different types of capacitors commonly used.
there is the fast switching type that the ESC mfg will supply. these act like a filter, smoothing out the spikes in the ESC power draw. this is happening at the drive frequency of the ESC. (fast like 10,000Hz or at least 1,000's) these are installed across the + and - ESC battery terminals.
the other cap is a slow discharge type that works like a storage device, these are used to avoid 'brown outs' in the BEC that can cause the spektrum receivers to reboot. the reboots of the latest spektrum recievers are so quick they seem like glitching. the original spektrums rebooted so slow they seemed to die and then come alive. these 'antiglitch' etc caps are usually equipped with a receiver plug, and the plug directly into the receiver.
