Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 249A is the minimum of the pass band attenuation amin . It is defined as the insertion
loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the
insertion loss ae. The nominal frequency fN is fixed on 249,6 MHz without tolerance. The given values for the relative attenuation arel and for the
group delay ripple have to be reached at the frequencies given below also if the centre frequency fc is shifted due to the temperature coefficient of
frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.

The minimum bending radius is 45 mm. The mounting surface of the filters faces the bottom side of the embossed carrier tape.
The marking of the filters is able to read if the view is directed on the upper side of the carrier tape with the sprocket holes on
the right side of the tape.
