Abstract
Ein induktives Bauelement für hochfrequente Schaltnetzteile kleiner Leistung weist eine Wicklung aus einer flexiblen Leiterplatte (2) auf. Die Leiterbahnen (3) sind dünn ausgebildet und untereinander versetzt. Dadurch werden Skin- und Proximityeffekte wirksam unterdrückt. An inductive component for high-frequency switching power supplies of low power has a winding made of a flexible printed circuit board (2). The conductor tracks (3) are thin and offset from one another. This effectively suppresses skin and proximity effects.
