A filter-choke to be used in an EMI filter, the filter choke comprising: - a closed magnetic core comprising two core-legs (21, 22), wherein the magnetic core is configured to be assembled out of at least two core-segments, - at least two bobbins, each bobbin comprising a base flange and a tubular section (32a, 32b) extending in perpendicular direction from the base flange, wherein the tubular section (32a, 32b) comprises an opening for receiving one of the two core-legs (21, 22), - a coil formed by an electric conductor having multiple windings arranged around the tubular section of each bobbin, wherein in an assembled state of the filter-choke, the bobbins are arranged in a stacked manner, such that their openings are aligned coaxially to each other, one of the core legs (21, 22) extending through the openings, and characterized in that each bobbin comprises at least two first fitting elements arranged on opposite edges of its base flange, wherein the first fitting elements of the first bobbin are configured to engage with the first fitting elements of the adjacent second bobbin for releasably fixing the two bobbins together, - wherein the at least two first fitting elements are each containing a part and a corresponding counterpart configured to form a snap fitting with the adjacent second bobbin, and - wherein for each first fitting element the snap fitting part and the snap fitting counterpart extend in opposite axial directions from the edge of the base flange. - a closed magnetic core comprising two core-legs (21, 22), wherein the magnetic core is configured to be assembled out of at least two core-segments, - at least two bobbins, each bobbin comprising a base flange and a tubular section (32a, 32b) extending in perpendicular direction from the base flange, wherein the tubular section (32a, 32b) comprises an opening for receiving one of the two core-legs (21, 22), - a coil formed by an electric conductor having multiple windings arranged around the tubular section of each bobbin, wherein in an assembled state of the filter-choke, the bobbins are arranged in a stacked manner, such that their openings are aligned coaxially to each other, one of the core legs (21, 22) extending through the openings, and characterized in that each bobbin comprises at least two first fitting elements arranged on opposite edges of its base flange, wherein the first fitting elements of the first bobbin are configured to engage with the first fitting elements of the adjacent second bobbin for releasably fixing the two bobbins together, wherein in an assembled state of the filter-choke, the bobbins are arranged in a stacked manner, such that their openings are aligned coaxially to each other, one of the core legs (21, 22) extending through the openings, and characterized in that each bobbin comprises at least two first fitting elements arranged on opposite edges of its base flange, wherein the first fitting elements of the first bobbin are configured to engage with the first fitting elements of the adjacent second bobbin for releasably fixing the two bobbins together, - wherein the at least two first fitting elements are each containing a part and a corresponding counterpart configured to form a snap fitting with the adjacent second bobbin, and - wherein for each first fitting element the snap fitting part and the snap fitting counterpart extend in opposite axial directions from the edge of the base flange.
