Contact UsDoes Capacitance Tolerance Matter? Significance And Impact
For example, if you have a capacitor with a nominal capacitance of 100 µF and a tolerance of ±10%, the tolerance range would be: Tolerance Range (ΔC) = 10% × 100 µF = 0.1 × 100 µF = 10 µF. This means that the actual capacitance of the capacitor could vary between 90 µF and 110 µF due to the specified tolerance.
