DielectricConstantCalc is your easy tool for working with capacitors and RC/LC circuits. Find one value for series, parallel, or mixed capacitor networks in seconds. Check energy stored at any voltage and see how fast circuits charge or discharge. Get the RC time constant to guide simple filters and timing parts. Figure out an LC resonant frequency for tuners, filters, or oscillators. See a capacitor’s AC impedance at your chosen frequency. Estimate breakdown voltage to set safe limits and pick parts wisely. Estimate a material’s dielectric constant from size and measured capacitance.
