(TCAC) Air Core Coils, Spring Inductors
Direct will do any custom coil windings of Air Coils (Spring Coils) for you. Direct manufactures all types of air coil inductors. Air Core Coils' another name is Spring Coils. Direct's Air Core Coil (TCAC) Series has advantages of free from iron losses, non-linearity, single layer coils structure, low self-capacitance, and self-resonant frequency.
(TCTC) Vertical base mounted Toroidal
Low Loss Powdered Iron Cores, Low EMI, High Current Toroidal Inductors. Direct'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). Direct toroidal can have higher Q factors and higher inductance than similarly constructed solenoid coils.
(TCFB) Inductor Ferrite Beads
Ferrite bead is a kind of anti-jamming applications the fastest growing components, cheap, easy to use, filtering high-frequency noise were improved significantly. Ferrite beads commonly used in filtering and electromagnetic noise reduction, Direct's Ferrite Beads TCFB series manufactured by using iron, nickel, zinc oxide mixture made with high resistivity and high magnetic permeability.
(TCWB) Wide Band Chokes
Excellent EMI Suppression Capability Wide Band Choke Coils (Inductor Filter). Direct's TCWB series use of insulation between the coil core winding method. To ensure that the transient over-voltage under the action of short circuit breakdown does not occur. And when the instantaneous high currents flowing through the coil, the core is not saturated.
