Notes
1.
Third harmonic typically exceeds other
harmonics by 10dB.
2.
Components are 100% tested at 6.5kV DC.
3.
Caution: do not pass DC through windings.
Telephone line current, etc. must be diverted
using semiconductor line hold circuit.
4.
At signal levels greater than 100mV, Lp will
increase and Rp will decrease slightly but the
effect is usually favourable to the return loss
characteristic.
