Characteristics  
Remark:  
The reference level for the relative attenuation arel of the TFS115M is the minimum of the pass band attenuation. This value is defined as the insertion loss  
ae. The nominal frequency fN is fixed at 115.2 MHz without any tolerance. The values of relative attenuation arel are guaranteed over the whole operating  
temperature range. The frequency shift of the filter within the operating temperature range is included in the production tolerance scheme.
