Abstract
A ferrite core, such as for transformers, has a middle bleb with an oval cross-section or flattened oval cross-section, whereby the longitudinal axis of the middle bleb is oriented parallel to the attachment plane of the transformer and the longest axis of the oval cross-section or flattened oval cross-section is oriented vertically to this attachment plane. The core is symmetrically structured with respect to a mirror plane, which contains the longitudinal axis of the ferrite core and which resides vertically to the attachment plane, and is particularly low in distortion.
