Power Inductor Toroidal Coils (TCTK)

Direct's Power Inductor Toroidal Coils with closed magnetic circuit for lowest EMI. Toroidal coils 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.

With vertical base mounted Direct TCTK series toroidal coils introduces advanced materials of iron core and special-purpose resins to produce the greatest inductance, high current, Lowest EMI, and Low cost. The TCTK is the most common kind of power inductors. Direct TCTK utilizes closed magnetic circuit design enabling the lowest EMI and is suitable for Copying Machine, Display Monitor, ADSL Modem, Refrigerator, Laundry Machine, Microwave Oven, Car Electronics, Gaming Machine, Color TV, Video Camera, and Air Conditioner.

Full line products meet RoHS compliant. Direct will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information. Download complete specification (TCTK) PDF (334KB)
