Calculate Capacitive reactance: 1F, 460kHz, kΩ
This calculation can calculate the capacitive reactance X
C of a capacitor knowing its capacitance and the frequency.
You can also calculate the capacitance knowing the desired reactance and frequency, or calculate the frequency knowing the capacitive reactance and capacitance.
X
C = 1 / (2πfC)
Enter any 2 values, the 3rd one will be calculated:

Some common standard frequencies:
Capacitive reactance formula says:
•The capacitive reactance (Xc) of a 1F (one farad) capacitor at 460kHz (four hundred and sixty kilohertz) is 345.9890067215nΩ (three hundred and fourty-five point nine eight nine zero zero six seven two one five nanoohms).
•For a 345.9890067215nΩ (three hundred and fourty-five point nine eight nine zero zero six seven two one five nanoohms) capacitive reactance at 460kHz (four hundred and sixty kilohertz), you need a 1F (one farad) capacitor.
•A 1F (one farad) capacitor would have a 345.9890067215nΩ (three hundred and fourty-five point nine eight nine zero zero six seven two one five nanoohms) reactance at 460kHz (four hundred and sixty kilohertz) frequency.
