Abstract:
(EN) This dust core 1, which is provided with a molded body 1B containing a soft magnetic powder MM and an exterior coat of the molded body 1B, and wherein the exterior coat contains at least one of a thermoplastic polyimide and a thermoplastic polyamide-imide, has excellent mechanical characteristics and is not susceptible to changes in the magnetic characteristics even if used in a high temperature environment. The exterior coat may have an impregnation structure. The present invention also provides: a method for producing this dust core; an electrical/electronic component which is provided with this dust core; and an electrical/electronic device which is equipped with this electrical/electronic component.
(FR) La présente invention concerne un noyau à poudre de fer (1), qui est pourvu d'un corps moulé (1B) contenant une poudre magnétique douce (MM) et un revêtement extérieur du corps moulé (1B), et le revêtement extérieur contenant un polyimide thermoplastique et/ou un polyamide-imide thermoplastique, qui présente d'excellentes caractéristiques mécaniques et n'est pas sensible aux changements de caractéristiques magnétiques même s'il est utilisé dans un environnement à haute température. Le revêtement extérieur peut avoir une structure d'imprégnation. La présente invention concerne également : un procédé de production de ce noyau à poudre de fer : un composant électrique/électronique qui est doté de ce noyau à poudre de fer; et un dispositif électrique/électronique qui est équipé de ce composant électrique/électronique.
(JA) 軟磁性粉末MMを含む成形体1Bと、前記成形体1Bの外装コートと、を備え、前記外装コートは、熱可塑性ポリイミドおよび熱可塑性ポリアミドイミドの少なくとも一方を含有する圧粉コア1は、高温環境下で使用されても磁気特性が変化しにくく、機械特性にも優れる。外装コートは含浸構造を有していてもよい。上記の圧粉コアの製造方法、該圧粉コアを備える電気・電子部品、および該電気・電子部品が実装された電気・電子機器も提供される。
