capacitor
The capacitor "loads down" the voltage from the power supply, thus creating a filter. simulate this circuit. In other words, the large capacitor on the circuit board is only half of the filter, another hidden half is the internal resistance of the power supply itself. When they''re combined, a voltage divider is created.
