Transformers
Transformer products are arrays of magnetically-coupled inductors in which the characteristic of the individual inductors within the array are typically non-uniform. They are most commonly used for either or both of two purposes; the conversion of AC power or signals between substantially different voltage levels, or the transmission of the same across the insulation barrier between two galvanically isolated circuits.
