Parallel Capacitor Total Capacitance
Use this parallel capacitor total capacitance tool when you have measured values for cap1, cap2, cap3. It applies a transparent mathematical relationship to those values to return an answer in µF. Unlike a prediction or recommendation, this is a calculation from your inputs. Parasitic capacitance and voltage ratings are not modeled. Enter a different scenario to see how this particular quantity changes; check the assumptions before using it in a project.
How to use this calculator
- Use exact measurements and consistent units for cap1, cap2, cap3.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported µF quantity against your own data and the limitations below.
Formula for Parallel Capacitor Total Capacitance
µF = cap1+cap2+cap3. Inputs are expressed in the units shown by the labels.
- This uses a direct electrical relationship and does not retrieve remote data, forecasts or individual account information.
- Parasitic capacitance and voltage ratings are not modeled.
Worked examples
Worked example — Parallel Capacitor Total Capacitance
Enter Cap1 = 10, Cap2 = 22, Cap3 = 47.
Apply cap1+cap2+cap3.
Calculated value: approximately 79 µF.
Understanding the result
The example produces about 79 µF; this is a mathematical output for the example inputs, not an observed result for your project.
Parasitic capacitance and voltage ratings are not modeled.
Important notes
Parasitic capacitance and voltage ratings are not modeled.
Use values from the same measurement period or physical system. The result is in µF and is not a guarantee of capacity, safety, ranking or revenue.
