Sintered core for transformer or inductor made of NiZn ferrite material

摘要

The invention describes a transformer core of NiZn ferrite material. Said transformer core exhibits low overall losses when it is used in a transformer. Said low losses are attained if the majority of the grains of the sintered ferrite material have a monodomain structure. This is the case if the average grain size is smaller than 2.8 microns. The average grain size of the sintered material preferably ranges of from 1.3 to 2.6 microns. The delta -value is preferably less than 4 nm. IMAGE
