本发明提供一种电感器,其系安装到柔性印刷电路板上时本身可以追随电路板的经时挠曲而变形、对摔落冲击的耐性高、且电感値高。本发明之电感器,系至少于空芯线圈的上面及下面的任何一面上,层积异向性复合磁性片而成的挠性电感器,其中该空芯线圈,系于平面内形成为螺旋状者,该异向性复合磁性片,系将具有长径方向及短径方向的扁平状或针状的软磁性金属粉末分散于树脂材料而成者,上述软磁性金属粉末的长径方向朝向上述空芯线圈的面内方向。
摘要(英):
A coil component is provided, and the coil component for an inductor is deformable dependent on flex of a flexible printed board due to elapse of time when mounted thereon, and has high resistance against dropping impact and has an inductance value. The coil component includes an anisotropic compound magnetic sheet which is layered on at least any one or both of the upper surface and the lower surface of an air core coil formed spirally in a plane and which is composed of flat or needle-shaped soft magnetic metal powder, which has a major axis and a minor axis and is dispersed in a resin material, the major axis of which corresponds to an in-plane direction of the air core coil.
