Remark:  
The reference level for the relative attenuation a of the TFS125S is the minimum of the pass band attenuation. This value is defined  
rel  
as the insertion loss a . The nominal frequency f is fixed at 125 MHz without any tolerance. The values of relative attenuation a are  
rel  
e
N
guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in  
the production tolerance scheme.
