Vertical and Horizontal Toroid Mounting Options

There are so many different reasons why electronic engineers choose custom toroids over other similar power transformers. There are many benefits and advantages these devices have, so they are amongst the most used power transformers for electronic devices. They are highly customizable, inexpensive to produce, and produce low noise. These devices are also easy to mount in existing structures. There are two methods of installing toroids: horizontal and vertical mounts. Below, we want to take some time to define the two types of mounting. If you have more questions, you should not hesitate to reach out to our talented team.


Horizontal mounts are used as a holder for mounting wound toroids on their side. Toroids can be attached to the mount with mechanical or adhesive means. For instance, cup-shaped toroid mounts are often filled with an encapsulating or potting compound that protects and mounts the toroid. It would help if you considered horizontal mounting when you require a low profile and a low center of gravity (applications that experience many vibrations and shock). It is important to keep in mind that horizontal mounting takes up valuable real estate on the circuit board.

Vertical mounts are attached with adhesives, encapsulations, or by mechanical means. A cup-shaped toroid mount can either be filled with a potting compound or through encapsulation. Both methods adhere and protect the core and winding. Use vertical mounting to save circuit board space as the diameter of a toroid gets larger. You need to factor in that this creates a component height issue. Vertical mounting, with all its benefits, does raise the device’s center of gravity, which makes it more susceptible to vibration and shock damage.
