Arrays, Signal Transformers FAQ

What is the difference between the rated current and saturation current?

Rated current indicates the maximum continuous current the inductor can handle without exceeding temperature limits, while saturation current is the point where inductance drops significantly due to core magnetic saturation.

Can the two coils be used independently?

Yes, the datasheet describes it as a two-coil array, allowing independent use or combined series/parallel connections depending on circuit design requirements.
