Magnetkern für Impulsübertrager und Impulsübertrager

摘要

A pulse transformer comprising a magnetic core formed of a thin strip of nanocrystalline soft magnetic alloy in which fine nanocrystalline grains having a grain size of not more than 50 nm occupy at least 50 volume % of the structure, characterized in that the AC relative initial magnetic permeability at -20 DEG C and 50 DEG C is not less than 50000.
