Series Capacitor Calculator

Series Capacitor converts the entered electrical measurements into equivalent capacitance. Use it to the equivalent capacitance calculation.

Enter values for equivalent capacitance

Use one consistent electrical operating case for all fields.

µF

Enter capacitor c1 in µF.

µF

Enter capacitor c2 in µF.

How Series Capacitor works

This worksheet evaluates Ceq = C1C2 ÷ (C1 + C2). Series Capacitor uses Capacitor C1, Capacitor C2 to report Equivalent capacitance.

With the loaded values, equivalent capacitance evaluates to 6.88 µF. Use separate cases for competing input values.

Inputs for Series Capacitor

Capacitor C1 and Capacitor C2 belong to Series Capacitor. Keep source units with capacitor c1.

Use the defaults to understand the output, then enter the real circuit or energy data.

Capacitor C1
Example entry: 10 µF.
Capacitor C2
Example entry: 22 µF.

Reading the Series Capacitor result

This output represents Series Capacitor.

Compare the output with equipment limits and the applicable design margins.

Measurement and units

Use component tolerances, voltage ratings, current limits, frequency behavior, and thermal data from the selected parts. Check prefixes on capacitor c1. If the next question concerns base current, open BJT Bias Calculator.

Do not compare cases built from different unit prefixes or measurement locations.

Limits of this calculation

Voltage sharing depends on leakage and tolerance.

Unlisted circuit behavior remains outside the computed result. Unentered effects remain outside Series Capacitor. Use Capacitor Charging Calculator as the follow-up for capacitor voltage.

A useful Series Capacitor comparison

Save the initial equivalent capacitance before adjusting capacitor C1. A low and high case is more informative than adding an unexplained safety factor after the calculation.

Document the alternate capacitor c1 source.
