1/ Qualification testing and approval to M27/103-01 shall be sufficient to grant qualification to M27/103-02
through M27/103-16.
2/ Impedance values written one above the other indicate a range of matching impedances over which the parts
will give satisfactory performance as long as the impedance ratio is maintained.
3/ Where windings are listed as SPLIT, one-fourth of the listed impedance is available by paralleling the winding.
