Title
(EN) INDUCTOR WITH THERMALLY STABLE RESISTANCE
(FR) INDUCTEUR AVEC RÉSISTANCE THERMIQUEMENT STABLE
Abstract
(EN)
An inductor 10, 100, 120 includes an inductor body 12, 102, 124 having a top surface 14 and a first 18 and second 20 opposite end surfaces. There is a void 28 through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element 30, 84, 98, 122 positioned through the void and turned toward the top surface to forms surface mount terminals 32, 34, 38, 40, 126, 128 which can be used for kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot 26. The resistive element may be formed of a punched resistive strip 84 and provide for a partial turn or multiple turns 94. The inductor may be formed of a distributed gap magnetic material 124 formed around the resistive element . A method for manufacturing the inductor includes positioning an inductor body 12, 102, 124 around a thermally stable resistive element such that terminals of the thermally stable restistive element extend from the inductor body.
(FR)
La présente invention concerne un inducteur (10, 100, 120) qui comprend un corps d'inducteur (12, 102, 124) ayant une surface supérieure (14) et une première (18) et une seconde (20) surface d'extrémité opposées. Un vide (28) traverse le corps d'inducteur entre la première et la seconde surface d'extrémité opposées. Un élément résistif thermiquement stable (30, 84, 98, 122) placé à travers le vide et tourné vers la surface supérieure forme les bornes de montage de la surface (32, 34, 38, 40, 126, 128) pouvant être utilisées pour le captage de type Kelvin. Lorsque le corps d'inducteur est constitué d'une ferrite, le corps d'inducteur comprend une fente (26). L'élément résistif peut être formé d'une bande résistive perforée (84) et fournir un tour partiel ou plusieurs tours (94). L'inducteur peut être formé d'un matériau magnétique d'intervalle distribué (124) formé autour de l'élément résistif. L'invention concerne un procédé pour fabriquer l'induction, qui comprend le positionnement d'un corps d'inducteur (12, 102, 124) autour d'un élément résistif thermiquement stable, de sorte que les bornes de l'élément résistif thermiquement stable se prolongent depuis le corps de l'inducteur.
