Calculate the reactance XC. Choosing a capacitor C and frequency f is best.
Capacitive reactance (symbol XC) is a measure of a capacitor's opposition to
AC (alternating current). Like resistance it is measured in ohms, but
reactance is more complex than resistance because its value depends on the
frequency (f) of the electrical signal passing through the capacitor as well
as on the capacitance, C.
Capacitive reactance, XC = 1 / (2 × π × f × C)
where: XC = reactance in ohms (ohm), f = frequency in hertz (Hz), C = capacitance in farads (F)
The reactance XC is large at low frequencies and small at high frequencies.
For steady DC which is zero frequency, XC is infinite (total opposition),
hence the rule that capacitors pass AC but block DC.
For example a 1 µF capacitor has a reactance of 3.2 kΩ for a 50 Hz signal, but
when the frequency is higher at 10 kHz its reactance is only 16 Ω.

Enter the values for capacitance and frequency, then press "calculate".
i want to connect capacitor to the Mains in Series with the another circuitry ( series Impedance application )
Now which type ( polypropelene ,Metalised Polypropelen ,Film Foil type AC) & make like vishay ,deki ,ctr?
i will calculate reactance value as per my need.
It can be of this type:
Thanks for prompt reply.
sir may i choose interference suppression x2 type of vishay make ?
Yes definitely you can use them!
simply calculate-1 mikrofarad on 230VAC,50 Hz is about 70mA
What is the meaning of c2 in your FM circuit? Please show me a photo of it.you said you can tune it with screw driver
gracias por la calculadora gracias por sus articulos le estoy siguiendo gracias por difundir conocimiemto util para nosotros le felicito por su loable gesto freddy sanchez managua nicaragua
Thank you! Appreciate your response very much!!
