For less than 10% error from operational amplifier,
((QO fO)/BW) < 0.1 where fo and BW are expressed in Hz.
If source impedance varies, filter may be preceded with
voltage follower buffer to stabilize filter parameters.
Given: fo = center frequency
A(fo) = gain at center frequency
Choose value fo, C
