Abstract

A rod core choke, for use e.g. in an electronic ballast of a fluorescent lamp, includes: a core (4) in the form of a rod having long and narrow solid shape, a sheath (bobbin 3) of an electrically insulating material surrounding said core (4) and a wire winding (2) around the said sheath (3), whereby said sheath (3) mutually insulates said core (4) and said wire winding (2). According to a preferred embodiment of the invention, said core is in form of a rod having parallelepiped shape.
