Capacitor Failures
Open mode failure. An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit. For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is directly applied to the circuit, …

power electronics
$begingroup$ each individual IC sees their own nearby bypass capacitor and to add to that: the fact that there is a capacitor nearby means that supply current spikes only need to travel in a short loop (remember that currents travel in loops). If the spike had to travel through the "far away" output capacitor of the buck converter, the loop would be much longer.

If new battery, 500 = CCR then ESR = 10 mohm and RC=T= 1000 s . The effect is that the ultracap being much lower ESR causes bigger surge currents on the 6 diodes in the alternator for the 3 phase alternator. The Caps act as near short circuit at 1 mohm being perhaps lower than the diode Rs improves peak voltage slightly under full load.
