C Cores are available in Lamination thickness usually of 0,30 mm, 0,l mm and 0,05 mm.
12、They are also usually supplied in “preferred“ strip width dimensions, ranging from 5 to 200 mm. As a broad guide a lamination thickness of 0,3 mm would be used for wound components at power frequencies in the 50/60 Hz band, 0,l mm at power frequencies in the 400Hz band, and 0,05 mm at high frequenci

17、agnetic oxide toroids with high permeability find use in a variety of components ie. pulse transformers, converter transformers, wide band transformer. It has the advantage that no audible noise occurs as a result of magnetostriction as with laminated cores. Due to the high saturation inductance, th
