Characteristics
Remark:
Reference level for the relative attenuation a
of the TFS 471A is the maximum of the pass band attenuation a . The maximum of the
max
rel
attenuation within the usable signal bandwidth is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper
and lower frequencies at the 3dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 471,55 MHz without
tolerance. The given values for the relative attenuation a and for the group delay ripple have to be reached at the frequencies given below also if
the centre frequency f is shifted due to the temperature coefficient of frequency TC in the operating temperature range and due to a production

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.
