2. Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS 35B is the minimum of the pass band attenuation amin. The minimum of
the pass band attenuation amin is defined as the insertion loss ae. The reference frequency fc is the arithmetic mean value of the upper and lower
frequencies at the 3 dB filter attenuation level relative to the insertion loss ae. . The nominal frequency fN is fixed at 35,42 MHz without tolerance.
All specified values are guarantied in operating temperature range.
