Reactance Chart                  Calculate any one value in a resonant circuit given the                  other two.                  Units:  MHz,nH,pF                  1. L                  2. C                  3. F                  Choose (1-3) [<Enter>=Quit] ? _

As an example, assume you have a 22 pF mica capacitor in hand, and you want to wind a small toroid, maybe on a Micrometals core, and want to make a high-Q trap at 100 MHz, What inductance do you need?

Here is the output calculation

                L      = 115.138 nH
                XL   = 72. 343 ohms
