When I added a filter to the limit switches on my StepPaks, I used a low
pass filter which included a resistor.  So once you select your capacitor,
just include a resistor to get the desired time constant.  If you don't
include your own resistor, then you are just using the output impedance of
the power supply to set your time constant.
