A toroidal transformer is used for a multitude of different electronic applications. The rule of thumb is that if housing can fit a toroid, then the device can use a toroid. In many situations, a toroid is ideal, but it is not also practical for specific applications.Read More

When you have a choice between a toroid and other similarly powered transformers, what is the right choice to make? Commercial and home devices (TVs, computers, audio systems) require small transformers of various core shapes. As devices get smaller and thinner, smaller transformers become more and more critical.

Making the proper considerations for inductor design is an integral part of designing toroids. Aside from the intended use of the device, there are a series of important factors that must be considered when specifying and designing an inductor.Read More

When you need to meet the modern-day needs for small, low magnetic interference field transformers, you should look no further than toroids. A toroid comes complete with a nearly ideal physical construction. A design engineer using these devices should expect excellent and reliable performance. A toroid is known to be small when compared to conventional transformers. A toroid can have less than 50% of the weight and size of other transformers.Read More

Learning about toroidal transformers is essential for understanding how they should be built and used. In this article, we want to take the time to address some critical design considerations and frequently asked questions. Read More

When comparing toroidal transformers and traditional transformers, toroids are typically known to have more benefits than their counterparts. Toroids have doughnut-shaped cores that are constructed from ferromagnetic materials (ferrite, laminated iron, and iron powder). Read More

Electrical engineers have many options when it comes to purchasing transformers. Considering the number of choices, how does someone know which is best for them and their applications? There are many factors to contemplate when picking a transformer type, but before making a decision, you should consider all the benefits provided by a custom toroidal transformer.Read More

When comparing a toroid to other similarly powered transformers, a toroid is considered highly efficient. The equation used for efficiency is Efficiency = Pout/Pin. Pin is the power input of a transformer, whereas the Pout is the measured output power that is delivered to a load. The difference between Pout and Pin is consumed by losses experienced inside the core and the windings. Toroids efficiently run at higher flux densities than E-I laminates. Their ideal magnetic circuit reduces the number of turns of wire wrapped around the core in cross-sectional areas. Custom coil winding of toroids creates efficiency rates that are consistently close to 95%. E-I laminates are less efficient than toroids, at around 90%.Read More

Engineers have many options for constructing transformers to be used inside of electronic equipment and devices. How do you know if you have chosen the right one? Much of the modern electronics used daily benefits from small transformers that have different core shapes. Each core shape boasts pros and cons, and so the various forms should not necessarily be used interchangeably.Read More

Toroidal transformers are considered passive electronic components that are constructed from magnetic materials built in a ring shape. The most common toroid materials include iron powder, laminated iron, and ferrite.  Considering the options for customization when creating these devices, it is essential for individuals to have some understanding of how these electronic devices operate.Read More
