Gapped toroidal coils usually require that the gap be filled with some type of insulating material to facilitate the

winding process. Split core current coils can be assembled directly on a conductor while toroids must be passed

over a disconnected end of the conductor.

Toroidal inductors are electronic components with the high performers among inductors, typically consisting of a

circular ring-shaped magnetic core of iron powder, ferrite, or other material around which wire is coiled to make

an inductor. Their windings cool better because of the proportionally larger surface area. Toroidal inductors with

a round core cross section are better performers than toroidal inductors with a rectangular cross section.

Token utilizes the latest micro gap toroid technology enabling the most cost-effective designs in manufacturing

through hole (TC19) products. Token’s TC19 Toroidal Series manufactured by Low loss powdered iron cores

offer the compact size and lower electromagnetic interference (EMI). Token toroidal can have higher Q factors

and higher inductance than similarly constructed solenoid coils. This is due largely to the smaller number of

turns required when the core provides a closed magnetic path. The magnetic flux in a toroid is largely confined

to the core, preventing its energy from being absorbed by nearby objects, making toroidal cores essentially

self-shielding. The TC19 series is suitable for a broad range of applications, such as high-frequency coils and

transformers.

Full line products meet RoHS compliant. Token will also produce devices outside these specifications to meet

specific customer requirements, please contact our sales for more information.
