TFS110D

Remark: Reference level for the relative attenuation a_rel of the TFS 110 D is the minimum of the pass band attenuation a_min. The minimum of the pass band attenuation a_min is defined as the insertion loss a_e. The centre (reference) frequency f_c is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss a_e.
