This value is defined as the insertion loss ae. The nominal frequency f N is fixed at 125 MHz without any tolerance. The values of relative attenuation arel are 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.
