Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 196 is the insertion loss. The insertion loss ae is defined as the insertion loss at the
nominal frequency fN . The centre 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 temperature coefficient of frequency Tc_f is valid both for the reference frequency fc and the frequency
response of the filter at the operating temperature. The frequency shift of the filter at the operating temperature not included in the production
tolerance scheme.

reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
