The audio transformer market is substantially growing in the current market scenario attributing to the advancements in the field of transformers. Also the advancements in the audio speakers field has led several companies to invest time and money in developing and integrating audio transformers, which is paving the growth of audio transformer market.

The increasing demand for electronics across the globe is pressurizing semiconductor manufacturers as well as electrical component manufacturers to constantly innovate and offer advanced products, which is creating a significant market space for audio transformer market in the recent years. The audio transformer market is poised to witness surge in the coming years, pertaining to the increased demand for miniaturized products from device integrators.

Filtering to meet emc requirements is now an essential requirement for many types of power electronic equipment. Two types of noise signal, common-mode and series-mode, are normally present, which require radically different types of suppression chokes to provide efficient filtering.

Introduction To Interference Suppression

Powder cores are a small but important family of materials that bridge the gap between low frequency strip cores and high frequency ferrite cores. Their unique combination of high saturation flux, relatively low core loss and distributed airgap makes powder cores an ideal solution for chokes and inductors used in many power conversion applications.

How Are Powder Cores Different

Because powder cores have properties that are at the same time both similar to and different from ferrite, we can take advantage of the differences to make chokes that take up less space and cost less. That applies to many choke types, including pfc chokes, output chokes and differential emc chokes. The difference is that they not only have a higher saturation, but it is also a “soft” saturation.
