EMI Toroid Coil Winding Toroidal Inductors Certificate Shape Copper Wire Material E496341 Certificate

Generally speaking toroidal inductors are more expensive than bobbin or tube wound inductors. Sufficient winding wire must first be wound (loaded) onto the winding shuttle, then wound onto the toroidal transformer’s core. (For bobbin/ tube wound wire is continuously de-reeled from a spool of wire.) After that, the best situation, from a cost perspective, is no insulation required over the winding. If the winding must be insulated, then it must either be insulated (taped) by hand or the toroidal inductor must be removed and taken to a separate taping machine. Some inductors have more than one winding. If additional windings are required, then the toroidal inductor is placed back on a toroid winding machine after taping. The shuttle must then be loaded with the wire size and type for the toroidal inductor’s next winding, thereby adding most cost to the inductor. Toroidal inductors with a single winding wound on a coated core may be cost competitive with an equivalent bobbin or tube wound inductor since the toroidal inductor will not require a bobbin or tube. The cost differential will then depend on the method and cost of mounting the inductors.
