Abstract (en)

[origin: EP0794541A1] A pulse transformer magnetic core comprising a magnetic core main body of a soft magnetic alloy ribbon having a thickness of 25 mu m or less, the AL value of the magnetic core main body being 4.0 mu H/N<2> or more when 0.1 V is input at 10 kHz. The magnetic core main body has an outer diameter of 10 mm or less and a thickness of 1.2 mm or less. The magnetic core main body may comprises by coiling the soft magnetic alloy ribbon or by stacking rings or E-shape and I-shape pieces which are made from the soft magnetic alloy ribbon by a punching process. <IMAGE>
