De-coupling capacitor and Bulk capacitor
There is, in a sense, no qualitative difference. The difference is one of scale, both of current and of time. A bulk capacitor is used to prevent the output of a supply from dropping too far during the periods when current is not available. For line-powered linear supplies, this would occur during the periods (say, 10s of msec) that the line ...

Types of Capacitors : Working and Their Applications
Select a capacitor with a working voltage three times higher than the power supply voltage. For example, if the power supply is 12 volts, use a 25 volt or 40-volt Capacitor. For smoothing purposes, it is better to take a high-value capacitor like 1000 uF to remove the ripples of AC almost completely.
