402 Products Found

We offer a wide range of toroidal inductors and coils, from 91nH to 4mH, with RMS current ratings from 240mA to 31.5A.

What is a Toroidal Inductor?

Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or doughnut) shape. They are passive electronic components, consisting of a circular ring or doughnut shaped magnetic core of ferromagnetic material such as laminated iron, iron powder, or ferrite, around which wire is wound.

Although closed-core inductors and transformers often use cores with a rectangular shape, the use of toroidal-shaped cores sometimes provides superior electrical performance. The advantage of the toroidal shape is that, due to its symmetry, the amount of magnetic flux that escapes outside the core (leakage flux) can be made low, potentially making it more efficient and making it emit less electromagnetic interference (EMI).

Types of toroidal inductor

Several types of toroid inductors and coils span multiple industries from music to medicine. Toroid inductors are often categorised by the following attributes:

  • Case size and dimension
  • Current rating
  • Nominal inductance
  • DC resistance
  • Packaging type
  • Tolerance

The cores are made from various materials such as silicon steel, nickel iron, iron powder and ferrites.

Applications for toroid inductors

Toroid inductors’ design advantages allow many applications in multiple industries. Security systems, power distribution equipment, automotive electronics, and renewable energy inverter systems all utilize toroid coils. Other industries that use toroid core windings are medical isolation material, telecommunication systems, industrial control equipment, and professional audio- and audio-visual equipment.

Toroidal inductors and transformers are also used in many other electronic circuits: power supplies, inverters, and amplifiers, which in turn are used in most electrical equipment: TVs, radios, computers, and audio systems.
