2. Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS 35A 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.
Measurement of filter response will be done at temperatures of –40°C , 25°C and 85°C for each part.

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as
reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
