Capacitor Dissipation Factor Calculator

To calculate the dissipation factor (DF) of a capacitor, divide the Equivalent Series Resistance (ESR) by the product of 2π, the frequency, and the capacitance. This gives the DF, which is a measure of energy loss in a capacitor.

The Capacitor Dissipation Factor Calculator helps you measure the efficiency of a capacitor by calculating its dissipation factor (DF). By using the capacitor’s ESR, frequency, and capacitance, the calculator determines how much energy is lost within the capacitor. This is critical for understanding the performance of capacitors in electronic circuits.

$DF = \frac{ESR}{2 \times \pi \times f \times$

Where:

DF = Dissipation Factor
ESR = Equivalent Series Resistance (in ohms)
f = Frequency (in hertz)
C = Capacitance (in farads)
π = Pi (approximately 3.14159)

Variable	Description
DF	Dissipation Factor
ESR	Equivalent Series Resistance (ohms)
f	Frequency (Hz)
C	Capacitance (Farads)
π	Pi (approximately 3.14159)

Example Calculation:

Let’s assume the ESR is 1 ohm, the frequency (f) is 1000 Hz, and the capacitance (C) is 10 µF (which is 10 × 10⁻⁶ F).

Using the formula:

$DF = \frac{1}{2 \times 3.14159 \times 1000 \times (10 \times 10^{-6})} = \frac{1}{0.0628318} \approx 15.92$

So, the dissipation factor is 15.92.

Step-by-Step Calculation:

Step	Calculation	Result
1	Multiply frequency by capacitance	$1000 \times 10 \times 10^{-6} = 0.01$
2	Multiply the result by $2 \times \pi$	$2 \times 3.14159 \times 0.01 = 0.0628318$
3	Divide ESR by the result of Step 2	$\frac{1}{0.0628318} = 15.92$

What is Capacitor Dissipation Factor Calculator ?

A Capacitor Dissipation Factor Calculator helps determine the efficiency and quality of a capacitor by calculating its dissipation factor (DF). The dissipation factor indicates how much energy is lost as heat within the capacitor during operation, which is important for understanding the performance of the capacitor.

The dissipation factor is often expressed as a percentage. For example, if you know the ESR and capacitance of a ceramic capacitor, you can easily calculate its dissipation factor using the formula above.

Using tools like the capacitor dissipation factor calculator ESR or calculate capacitor ESR from dissipation factor, you can measure the DF of a capacitor or find the ESR from a datasheet. These measurements are crucial for applications where high precision and minimal energy loss are required, such as in RF circuits and power supplies.

The dissipation factor of materials can also affect the performance of capacitors. By understanding the dissipation factor of a capacitance measurement, you can ensure that the capacitor functions efficiently within its designed parameters.
