The CAR coupling balun transformer CAR-CNB1 is used for immunity testing against line-to-line coupled fast transients a balun according to e.g. ISO/ 7637-4:2020. A simple transmission line transformer providing the unbalanced to balanced mode transformation is shown in figure. Both terminals on the balanced side are terminated with 50 Ω to ground.
