Title
(EN) MINIATURE POWER INDUCTOR AND METHODS OF MANUFACTURE
(FR) INDUCTANCE DE PUISSANCE MINIATURE ET PROCÉDÉS POUR SA FABRICATION
Abstract
(EN) Magnetic components such as power inductors for circuit board applications include pressure laminate constructions involving flexible dielectric sheets that may integrally include magnetic powder materials. The dielectric sheets may be pressure laminated around a coil winding in an economical and reliable manner, with performance advantages over known magnetic component constructions.
(FR) L'invention concerne des composants magnétiques, comme des inductances de puissance, destinés à des applications sur cartes à circuits et comprenant des constructions stratifiées sous pression faisant intervenir des feuilles diélectriques souples susceptibles de comprendre de manière intégrée des matériaux magnétiques en poudre. Les feuilles diélectriques peuvent être stratifiées sous pression autour d'un enroulement de bobine de manière économique et fiable, et présentent des avantages en termes de performances par rapport aux composants magnétiques de construction connue.
