High Current Toroidal Inductors (TCTC)
Toroidal inductors and transformers 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 coils with a round core cross section are better performers than a rectangular cross section.
DeMint's (TCTC) high current Toroidal Series manufactured by Low loss powdered iron cores offer the smallest size by volume and weight, and lower electromagnetic interference (EMI). DeMint 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 (TCTC) series is suitable for a broad range of applications, such as high-frequency coils and transformers.
Full line products meet RoHS compliant. DeMint will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
