Aluminum electrolytic capacitors are great for controlling surges in high-power buses. This is a Panasonic capacitor with part number: EEU-FM1E470. You can view the datasheet here. These are Panasonic FM Series capacitors, which is their best series in terms of impedance and maximum ripple current. FM Series capacitors can handle 2-3 times the ripple current as a similar-size general purpose electrolytic capacitor. Their very low impedance values means they can absorb and release large amounts of energy very quickly.
A 47uF capacitor is usually capable of suppressing surges to a satisfactory level in power buses carrying several amps (although there are many factors to take into consideration).
