Abstract
An inductive component intended to be installed on a printed circuit includes at least one winding, a body, and a magnetic core. The winding is made of an electrically conductive wire wound to form a flat coil the ends of which are connected to the inner ends of connecting terminals. The body is formed from a block of insulating material over-moulded onto the coil and onto the said inner ends of the terminals, the body including a central opening which passes through the body along the axis of the coil. The magnetic core is made of a ferrite layer that surrounds the body in a center plane containing the axis of the coil. A center element passes through the opening in the body.
Claims7
An inductive component intended to be installed on a printed circuit, comprising:
- first and second connecting terminals for connecting the inductive component to the printed circuit, the first and second connecting terminals having inner ends;
- a conductive electric wire having a first end operatively connected to the inner end of the first terminal and a second end operatively connected to the inner end of the second terminal, the wire wound about an axis to form a coil having a shape;
- a coating about the wire for retaining the shape of the coil;
- a body formed from a block of insulating material having a lower face orthogonal to the axis, the body being overmoulded onto the coil and onto the inner ends of the first and second terminals and defining a central opening therethrough which extends along the axis;
- and
- a magnetic core positioned between the first and second connecting terminals, the magnetic core being formed of ferrite and having a central element passing through the central opening through the body.
