Abstract (en)

The HF interference current suppression device uses an inductance through which the operating current is passed, provided by an annular core (7) of an amorphous or nano-crystalline material with a relative permeability of above 20000. The core is fitted over a pin (4) within a plug connector housing (1). A capacitor can be connected between the operating current lead and earth, with the annular core insulated relative to the pin and connected to earth, so that it acts as a capacitor electrode.

Abstract (de)

Zur Verminderung von insbesondere hochfrequenten Störspannungen werden amorphe oder nanokristalline Ringbandkerne (7) auf Stifte (4) innerhalb des Gehäuses (1) einer Steckverbindung aufgebracht. Hierdurch läßt sich die elektromagnetische Verträglichkeit von elektronischen Komponenten in einem weiten Frequenzbereich verbessern. <IMAGE>
