NOTES:

Source impedance - All models have a source impedance of 50R
Load impedance - In the above tables this is assumed to be >50k
50R load - With a 50R load I-t capability is increased by between 20% and 80% and droop and lf cut-off point are reduced by a factor of 0.6 to 0.85. A 50R load at the receiver and a 50R line should be used where long cables are employed or where the highest frequency response is required.
Output – Accuracy +/-0.5% at mid-log frequency point, +/-2% within one decade of 3dB cut-off points. The use of a 50R load will halve the sensitivity
I-t No bias – Lilco broadband current transformers do not require the application any biasing current to achieve this level of I-t. The use of a 50R load will enhance the I-t capability significantly.
I-t with bias – these levels are achieved with a dc off-set current equal to Isat. The use of a 50R load will enhance the I-t capability further
Price – small quantity price, 1-2 off
58M0020 and 58D0020 – these broadband current transformers have been introduced to satisfy the measurement demands of EN61000-4-11
