Abstract
An SMD inductor as a component and a method for producing an SMD inductor. The inductor simultaneously has low losses and a high peak current-carrying capacity and also a high mechanical stability. To that end, it includes an inner core piece, an outer core piece and a coil having a wire. The inner core piece includes an alloy. The outer core piece includes ferrite. The wire is wound around the inner core piece, and the inner core piece with the wire is arranged in the outer core piece.
Claims13
An SMD inductor having a high peak current-carrying capacity and low losses, comprising
- an inner core piece, an outer core piece and a coil having a wire, wherein
- the inner core piece comprises an alloy,
- the outer core piece comprises ferrite,
- the wire is wound around the inner core piece,
- the inner core piece with the wire is arranged in the outer core piece.
A method for producing an SMD inductor, comprising the following steps of:
- providing an inner core piece composed of an alloy, an outer core piece composed of ferrite, and a wire,
- winding the wire onto the inner core piece to form a coil,
- arranging the inner core piece with the coil in the outer core piece,
- interconnecting the coil with external terminals.
