Simply enter the values of capacitance, voltage in our basic and advanced calculator to get the results!
Welcome to the Capacitor Value Calculator! Capacitors are essential components in electronic circuits, storing electrical energy and regulating voltage. It helps in determining the value of capacitors based on their code or markings. Capacitors like 104 capacitors or 106 capacitors have specific values that can be read using this tool. It supports calculating SMD capacitor codes, ceramic capacitor values, and provides an easy way to decode and understand capacitance in circuits
Formula:
The formula is:
| Variable | Meaning |
|---|---|
| CV | Capacitor Value (in farad-volts or μF-V) |
| C | Capacitance (in farads or microfarads, μF) |
| V | Voltage (in volts) |
How to Calculate ?
To calculate the Capacitor Value (CV):
- Multiply the capacitance (C) by the voltage (V) applied across the capacitor.
- This result gives the value of the capacitor in farad-volts or microfarad-volts, which is a measure of how much energy the capacitor can store.

What is Capacitor Value ?
A Capacitor Value Calculator is an essential to determine the value of capacitors in circuits. Capacitors have a wide range of values, from picofarads (pF) to microfarads (µF), and their values can be read using different coding systems. For instance, a 104 capacitor value refers to 100,000 pF, or 0.1 µF.
To determine a capacitor’s value, the calculator decodes the markings on the capacitor, such as SMD capacitor codes or ceramic capacitor codes.
To check a capacitor’s value, you can refer to the capacitor color code chart or input its numerical code, like 222, which translates to 2200 pF (or 2.2 nF). The capacitance formula is crucial in calculating how much electrical charge a capacitor can store.
For example, the 106 capacitor represents 10,000,000 pF, or 10 µF. When working with capacitors in circuits, the capacitor value calculator aids in determining the appropriate capacitance needed for applications such as filtering, blocking DC, or stabilizing voltages.
Capacitors with the highest values, such as electrolytic capacitors, are used in applications requiring large charge storage. Understanding these values is essential for circuit design, and the calculator simplifies this process.
