Abstract

L'invention concerne un dispositif de filtration de la tension d'alimentation d'un bloc électrique, en particulier dans un composant de véhicule automobile, lequel dispositif est muni d'au moins un composant électrique ou électronique de déparasitage monté en surface (14), ayant une fonction de déparasitage et/ou contribuant à une fonction de déparasitage, et d'une carte de circuits imprimés (22) qui comporte deux côtés principaux (20, 24) et sur laquelle le composant de déparasitage monté en surface (14) peut être positionnée en tant que partie d'un circuit électrique. La fonction de déparasitage que doit réaliser le composant de déparasitage monté en surface (14) est remplacée par deux éléments (16, 18) du composant de déparasitage monté en surface (lesquels ont sensiblement une configuration identique) qui sont reliés électriquement entre eux. L'un des éléments (16, 18) est disposé sur l'un des côtés principaux (20, 24) de la carte de circuits imprimés (22) et l'autre élément (16, 18) est disposé sur l'autre côté principal (20, 24) de la carte de circuits imprimés (22), à savoir à l'opposé l'un de l'autre et en alignement l'un avec l'autre lorsque l'on regarde la carte de circuits imprimés (22) en direction de l'un des deux côtés principaux (20, 24).
