High Saturation Current
In characteristic current mode inductors, however, the high saturation current is a point of saturation, indicated by what is called I-sat, and it represents a practical limit on how much current the inductor can pass before losing its impedance properties and becoming virtually useless. When common mode inductors offer variable saturation current, like the above-mentioned high saturation current, it is possible for them to deliver higher current levels with no effect on performance. This makes common-mode inductors well-suited for such applications as power supplies and industrial systems. On the one hand, this characteristic can ensure the inductors continued and reliable performance under demanding conditions. On the other hand, it can prolong the life of customers electronic equipment, giving them peace of mind.
