A toroidal transformer is a good thing to have if you are looking for an efficient way to transfer electrical energy away from one circuit and toward another while maintaining a steady frequency. In order to do this, toroidal transformers take advantage of electromagnetic induction. This kind of transformer is useful because it is highly efficient and the small magnetized portion does not greatly affect any of the other components.

Each toroidal transformer is built with a core that is made from silicon, iron, ferrite, or another similar material. This core is ring-shaped in order to eliminate any air gaps. Coils are wrapped around the core so that they cover the entirety of its either square or rectangular cross-sectioned shape. This process greatly minimizes the strength of the magnetic field created by the core thereby making the level of interference with other parts of the machinery insignificant.

If you have decided to use this type of transformer it is likely because they are smaller, lighter, quieter, and more variable in shape than other types. You are probably in need of a toroidal transformer with a specific primary configuration or frequency and a particular maximum primary voltage rating. To be even more specific, you will need to find one with a certain output type, an appropriate maximum power rating, and an ideal maximum secondary current and voltage rating. Even after meeting all those specifications, you may require a specialized mount for your particular usage.
