    • A method of producing a surface-mount inductor by encapsulating a coil with an encapsulation material containing a resin and a filler using a mold die assembly is provided. In the method, a tablet and a coil are used. The tablet is prepared by preforming the encapsulation material into a shape having a flat plate-shaped portion and a pillar-shaped convex portion on a peripheral thereof. The coil is a wound conductive wire having a cross-section of rectangular-shape. The coil is placed on the tablet to allow both ends of the coil to extend along an outer side surface of the pillar-shaped convex portion of the tablet. The coil and the encapsulation material are integrated together while clamping the both ends of the coil between an inner wall surface of the mold die assembly and the outer side surface of the pillar-shaped convex portion of the tablet, to form a molded body. External electrodes are formed on a surface of or around an outer periphery of the molded body in such a manner that the external electrodes are electrically connected to the both ends of the coil at least a portion of which is exposed to the surface of the molded body.
    • 提供了一种通过使用模具组件将包含树脂和填料的封装材料封装在一起的线圈来制造表面安装电感器的方法。 在该方法中,使用片剂和线圈。 通过将封装材料预成型为在其周边具有平板状部分和柱状凸部的形状来制备片剂。 线圈是具有矩形截面的缠绕导电线。 线圈被放置在片剂上以允许线圈的两端沿着片剂的柱状凸部的外侧表面延伸。 线圈和封装材料在将模具的内壁表面与片剂的柱状凸部的外侧表面夹紧在一起的同时将线圈的两端夹紧在一起,以形成模制体。 外部电极形成在成型体的外周的表面上或外周电极上,使得外部电极电连接到线圈的两端,其至少一部分暴露于成型体的表面 。
