Capacitor Size for a DC motor. Do I even need one?
The voltage can be smoothed with a capacitor only after the inductance - in your case impossible. The motor can exhibit torque ripple due to the current ripple and not due voltage ripple, so the capacitor is never needed. Right the opposite, if you want a very smooth current then you need to add yet another big choke.
supercapacitor
The supercaps are 0.16F (for one pair of 0.33F in series) The maximum voltage on the caps is about 8.75 . The minimum voltage at which your output is regulated is (3.3 + 1.5 + 0.25) = 5.05V . At 150mA load, this should translate into approximately 3.5 seconds of backup capability and assuming decent caps with ESR less than 1 Ohm.
How to Test a Capacitor on a Circuit Board?
How many ohms should a capacitor have? A capacitor should not have any ohms. This is because capacitors are designed to not have any electrical resistance, so if it reads 0 ohms then something has gone wrong with the component. If a capacitor reads anything other than 0 ohms, it means that the device has failed and should be replaced.
