No marking CFS-145 CFS-145 CFS-145 CFS-145 BB BB 6.0pF FF FF 12.5pF (STD) VV VV 8.0pF YY YY 7.0pF Hold the body of crystal unit by hand, and the part to be bent with tweezers leaving more than 1.5mm of lead from the body case. (3.0mm is recommended) Bend the lead 90°holding with the tweezers. Pulling the lead strongly may crack the hermetic seal glass at the root of the lead and may cause the airtightness and the characteristics to deteriorate. 22 : Manufacture's ID Code CFS-206 CFS-206 CFS-206 CFS-206 Nov Dec ■ Part Marking [standard] y : The last digit of production year m : Production month (See Table.1) # : Production Lot No. Table.1 ■ PART NUMBERING SYSTEM ZZ ZZ Standard Spec.
