    hi guys,

    can someone tell me the capacitance and inductance for a 1 MHz resonator/oscillator

    your neighborhood genius

    http://en.wikipedia.org/wiki/RLC_circuit" [Broken] It's under resonance frequency.

    You'll have to start with an assumption. Assume one of the following three, and you can solve for the others:

    X of C and L

    At resonance, Xc = XL = 2*pi*f*L = 1/2*pi*f*C

    You could try these:

    16 uH....... 1592 pF

    24 uH ....... 1061 pF

    32 uH ...... 796 pF

    Try to download the following program:

    I set the reactance to about 200 ohms and let the program work out suitable L and C values.
    Watch the units.

    Then the hard part is finding suitable inductors. The ferrite rod antenna in transistor radios resonates at 1 MHz with about 200 pF.
