1. Resistor should be non-inductive and selected to carry secondary rms and pulse currents.
2. The sensitivity is determined from the relationship Output = Secondary resistor value / ratio. The ratio may be deduced from the resistor values and sensitivities in the data talbe. Current ratio accuracy within +1% / -3% within one decade of the 3db cut-off points.
3. I-t capability may be improved up to 80% by applying a dc offset current equal to Isat. See “Characteristics” section.
4. High frequency properties achieved when secondary resistor is connected to a 50R cable via a resistor designed to make the source resistor equal to 50R. A 50R terminating resistor is employed at the receiver. It may be necessary to screen the transformer in some applications.
5. Small quantity price.
