Abstract: A soft magnetic laminated core is provided which comprises first laminations and second laminations arranged in a stack having a stacking direction substantially perpendicular to a major surface of the first laminations and the second laminations. The first laminations comprise a first soft magnetic alloy and the second laminations comprise a second soft magnetic alloy different from the first soft magnetic alloy. The first laminations and the second laminations are distributed in the stacking direction throughout the stack. The first laminations and/or the second laminations comprise an insulating coating that is thermally stable up to at least 850° C.
