FT140-63

MATERIAL 63 (Permeabilität 40)

Ein Nickel-Zink-Material ausgezeichnete Stabilität und einen erweiterten Frequenzbereich von 10 bis 80 MHz sowie eine höhere Flußdichte gegenüber Material 63, dagegen einen etwas niedrigeren Volumenwiderstand. Sehr gut geeignet für HF-Anwendungen hoher Güte. Wird verbreitet für Breitbandverstärker und Linearendstufen eingesetzt. Lieferbar in Ringform.
