Note1: ILmin is the minimum of the pass band attenuation. The center frequency Fc is the mean value
of the upper and lower frequencies at the 3dB filter attenuation level relative to the ILmin.
Note2: The room temperature, Tr, is 25°C. FTC is temperature coefficient of frequency. The nominal
frequency at temperature, Tc, may be calculated from f= Fc [1-FTC(Tr-Tc)].
