Arrays, Signal Transformers FAQ

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

Rated current indicates the maximum continuous current before excessive heating occurs, while saturation current is the point where inductance drops significantly due to core magnetic saturation.

How does the connection mode affect the inductance value?

In parallel connection, the inductance is 33.92 µH. In series connection, the inductance increases to 135.7 µH due to the additive nature of the coupled coils.
