If you refer to the capacitance that is generally placed across from pins that I think are labeled "V+" and "V-", the typical value is 0.1uF or less, and the typical type is ceramic, because you want a capacitor that does not become inductive at very high (ultrasonic) frequencies. Are you looking at a schematic? If not, why do you want to use such a large capacitance? It's also important to keep the leads short, which may be difficult with such a large part. It might even be a negative to use such a large value.
