TOKEN TC19 Power Gap Toroidal Inductors Through Hole Gap Toroidal Inductors Through Hole Gap Toroidal Coils Make Your Design More Cost-Effective (TC19) Preview 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.
