Characteristics  
Remark:  
Reference level for the relative attenuation a of the TFS 125K is the maximum attenuation in the pass band. The maximum attenuation in the  
rel  
pass band is defined as the insertion loss a . The nominal frequency fN is fixed at 125 MHz without tolerance or limit. The values of relative  
e
attenuation a  
are guaranteed in the whole operating temperature range. The frequency shift of the filter in the operating temperature range is  
rel  
included in the production tolerance scheme.
