Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 248 B is the minimum of the pass band attenuation amin. The
minimum of the pass band attenuation amin is defined as the insertion loss ae.The nominal frequency fN is fixed on 248,450
MHz without tolerance.

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.
