Capacitor calculator | Capacitance calculator

This page covers capacitor calculator used to calculate capacitance. This capacitor calculator takes surface area, distance between plates and dielectric as input and calculates capacitance as output. The capacitor formula used for the capacitance calculator is also mentioned.

Dielectric constant K as per table (input1) :

Surface Area of plates in mm2(input2) :

Distance between plates in mm (input3) :

Capacitance in Farads (output1) :


*Note: Enter values in INPUT boxes and Press CALCULATE button to check OUTPUTS.

EXAMPLE of capacitor calculator:
INPUTS: K = 2.53, A = 0.5 mm2 , D = 0.005 mm
OUTPUT: Capacitance = 2.24 x 10-12 farads or 2.24 PF


Capacitor formula used for capacitor calculator

Following equation or formula is used for this capacitor calculator.

C = K * Eo * A/D

Where,
K = Dielectric constant of material, refer table-1 and table-2 below to select numeric value as per material

Eo = 8.854 x 10-12

A = Overlapping surface area of the plates

D = Distance between the plates
