following formula:
2.The maximum current rating is based upon temperature rise of the

5. For RoHS compliant parts add suffix NL to the part number.
3. To calculate the value of the terminating resistor (Rt) use the following
6.Add T suffix to the part number for tape and reel packaging.
formula: Rt () = Vrfe * N / (Ipeak_primary)
