NOTES:
*1) Where primary is center-tapped, this figure is the maximum unbalance
*2) When operating at impedances below normal, power capability and the frequency spectrum are proportionately lower,
*3) Insertion loss measured at 1000 Hz.
*4) Approximate frequency in hertz at which the output, at rated load and D.C. unbalance, is 1 db below the 1000 Hertz rating.
106EE
conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.
The high frequency roll-off point exceeds 20 Khz. (Above 35 Khz. in most types).
