But large capacitors can affect the stability of op-amps or switching regulators. And they can give rise to large inrush currents when power is first connected to a circuit. Even if the inrush can be accommodated, it may cause the power source Voltage to droop, and if other circuitry is attached to that power source, it may reset or malfunction due to the droop.
