Arrays, Signal Transformers

Transformer-type inductor arrays are inductors having two or more windings which are not electrically connected internally, but which are magnetically coupled within the device. Also known as coupled inductors, the choice of external connection allows their use for different purposes such as common or differential mode filtering and voltage transformation.
