TFS248F

      The TFS248F has the following features including Ambient temperature: 23;Input power level: 10 dBm;Terminating impedances : input: 50 ; unbalanced; no matching network,output: 200 ; balanced, no matching network.
      Reference level for the relative attenuation arel of the TFS 248 F 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 at 248,6 MHz. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even 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.Markings on the filters can be read if the upper side of the carrier tape is regarded with the sprocket holes on its right.
      Tape & Reel: IEC 286 - 3, with exception of value for N and minimum bending radius; tape type II, embossed carrier tape with top cover tape on the upper side; max. pieces of filters per reel is 3000;reel of empty components at start is min 300 mm;reel of empty components at start including leader is min 500 mm;trailer is min 300 mm.VI TELEFILTER reserves the right to make changes to the product(s) and/or information contained herein without notice No liability is assumed as a result of their use or application.No rights under any patent accompany the sale of any such product(s) or information.
