The optimal shape of the ring core or toroid can benefit transformers by increasing efficiency and reducing size and weight when compared with other constructions.

The jointless magnetic path of continuous ribbon toroids provides high inductance and reduced acoustic noise.

As the magnetic flux is in the preferred direction throughout the magnetic circuit core losses are minimized.

Meanwhile powder cores provide the ideal distributed gap in energy storage inductors.

Because of the symmetry of toroids the external field produced is much reduced and susceptibility when the device is itself exposed to magnetic field is similarly diminished.

Toroids offer dimensional versatility and generally result in low profile components.

Mounting options include a dished washer with centre screw, resin filled centre with insert and bonding to a panel with pins.

Although not a panacea, because there are disadvantages, toroids are often an appropriate choice and will be recommended when the advantages can be exploited.

Their use is widespread and they found in all sectors of electronics.
