Econo-Pac™ Series, Arrays, Signal Transformers

Transformer-type inductor arrays consist of inductors with two or more windings that are magnetically coupled within the device, without internal electrical connections between the windings. These components are also referred to as coupled inductors due to the magnetic coupling between the individual windings. The absence of internal electrical connections enables the independent use of each winding for specific purposes. This flexibility allows transformer-type inductor arrays to be employed for various applications, including common mode filtering, differential mode filtering, and voltage transformation. Common mode filtering involves suppressing unwanted electromagnetic interference or noise that appears in common mode across multiple signal lines. Transformer-type inductor arrays can effectively reduce this interference by utilizing the magnetic coupling between windings to filter out common mode signals. Differential mode filtering, on the other hand, targets interference that appears differentially between pairs of signal lines. By leveraging the separate windings within the inductor array, these components can mitigate unwanted differential mode noise, contributing to improved signal integrity and reduced distortion. In addition to filtering applications, transformer-type inductor arrays are capable of voltage transformation. The independent external connections allow for the application of different input and output voltages across the windings, enabling voltage conversion or adaptation to suit specific circuit requirements. The versatility of transformer-type inductor arrays makes them valuable components in electronic circuits, offering engineers the flexibility to address various signal integrity and power management challenges. Whether it's for filtering electromagnetic interference or adapting voltage levels, these inductor arrays provide a practical and efficient solution for diverse circuit design needs.
