Producing one cut core and one "I" bar requires less tooling and is less time consuming than two cut cores, therefore the C-I core is less expensive to make than two cut cores. The ease of copper coil winding. Since the "'I" bar is straight and has flat surfaces, the copper coil can be wound directly onto the "I" bar without having to make a bobbin. This will reduce the cost and simplify the production of prototypes significantly. Reduction of the winding resistance. Since the "I" bar is removable, it can be smoothed out around the four edges (optional ) where the copper wires are wound which would reduce the the wire length and ultimately reduce the resistance of the winding. Adjustable air gaps : For Inductors requiring air gaps, the insulation can be placed onto the "I" section to be used as air gaps. Tighter tolerance: The tolerance only applies to one cut core instead of two as in the shell type, and the "I" bar is made of stacked up lamination in which the tolerance can be more accurately controlled to fit the bobbin. Efficient assembly time: Normally the transformer using double cut cores required two clamping bands on each individual core as shown in Figure 2. The C-I core is held together by one clamping band as in Figures 3a & 3b "C-I Core" Page 1 | 2 | 3 | 4 | 5 | 6
