Abstract

1. A method for the production of an inductive component comprising a toroidal strip-wound core (7) which is inserted into a container (1) consisting of insulating material so that the toroidal strip-wound core (7) is enclosed by the container (1) at one end face and - at least partially - on the inside and outside and at least one winding which surrounds the toroidal strip-wound core and is formed by electrical conductors bent into a U-formation, characterised in that in order to form the winding, individual rectilinear pins are inserted or cast into the container (1) and after the insertion of the toroidal strip-wound core (7) into the container (1), are bent outwards over the toroidal strip-wound core (7) into a U-shape, and that when a cap (9) has been placed in position, the pins (3), which have been bent into a U-shape, are fixed in grooves (10) arranged on the outside of the container (1).
