Air copper coils and chokes are being designed similarly to straight ends torsion springs using helical winding and legs (terminals) serving to make contact with other components. During the production process, these inductive elements are CNC coiled, their polish insulation is cleaned and then the surface is tinned by lead-free solder. For chokes production, we use NiZn and MnZn ferrite cores of number of sizes and composition elements’ ratio.
Inductive elements such as air copper coils and chokes are mainly applied in electrical engineering and electronics and represent a passive element with fixed or adjustable value of inductance. In the most common case, inductive element represents a coil of electrical wire and when a current flows in the conductor of the coil, a magnetic field occurs. Due to their ability to convert alternating current (AC), coils are among the main components used in electrical circuits, in which circuit and voltage change over time.
More precisely, air copper coils find application in automatic circuit-breakers and printed circuit boards (PCB). Anti-interference chokes on the other hand are used for integration in electrical controlled motors (brush engines), for blocking the interference processes affecting the vehicles electronics or as primary coils for high voltage transformers.
