1/ Impedance values written one above the other indicates a range of matching impedances over which the parts will give
satisfactory performance as long as the impedance ratio is maintained.
2/ Where windings are listed as split, one-fourth of the listed impedance is available by paralleling the winding.
3/ Electrostatic shield, shield ratio 5:1 minimum at 20 kHz.
4/ Qualification testing and approval to M27/167-01 shall be sufficient to grant qualification approval to M27/167-01
through M27/167-42, inclusive.
