Can capacitors with different capacities and the same voltage be used in parallel? Can Combine capacitors in parallel?

Calculating the total capacitance of two or more capacitors in parallel is simple: Just add up the individual capacitor values to get the total capacitance.

This rule makes sense if you think about it for a moment. When you connect capacitors in parallel, you’re essentially connecting the plates of the individual capacitors. So connecting two identical capacitors in parallel essentially doubles the size of the plates, which effectively doubles the capacitance.

Whenever you see two or more capacitors in parallel in a circuit, you can substitute a single capacitor whose value is the sum of the individual capacitors.

However, in most cases,the total capacitance of capacitors in parallel is always greater than the capacitance of any of the individual capacitors. That’s because each capacitor adds its own capacitance to the total.

Summary: We do not suggest to combine capacitors, as the more capacitors you combine,  the bigger total capacitance you will get. Usually you have to choose the single right capacitance capacitor for your application. 

Simulation Test：Combined three pieces of 10uF 100V WMH - Pure Foil and Film Audio Capacitors + one piece of 6.8uF 100V WMH - Pure Foil and Film Audio Capacitor, total capacitance is 37.24uF, which is within specification and capacitance tolerance.

Tips: Based on testing temperature, environmental humidity and testing equipment factors, the capacitance will has slight difference, but it will still be within specification. We suggest customer use professionally testing equipment to check the capacitance, such LCR test instrument or Oscilloscope, rather than a multimeter.
