摘要： A wire-wound type chip coil can take various inductance values while maintaining its outer dimension at a specified fixed value. A chip coil is formed by winding at least two conductive wires regularly in a single layer around a core made of a magnetic material and firmly connecting both ends of each conductive wire to terminal electrodes disposed on respective flanges of the core. This makes it possible to obtain a great current capacity. Furthermore, the inductance decreases because of an increase in the magnetic path length. A great number of different inductance values can be easily obtained by properly selecting parameters including the number of substantially parallel conductive wires, the diameter of each conductive wire, and the number of turns.
摘要翻译： 线绕型芯片线圈可以采用各种电感值，同时将其外形尺寸保持在规定的固定值。 通过在由磁性材料制成的芯周围的单层中规则地缠绕至少两根导线并将每根导线的两端牢固地连接到设置在芯的相应凸缘上的端子电极而形成芯片线圈。 这使得可以获得大的电流容量。 此外，由于磁路长度的增加，电感减小。 通过适当地选择包括基本平行的导线的数量，每个导线的直径和匝数的参数，可以容易地获得大量不同的电感值。

摘要： An electronic device such as a chip coil including an electric wire firmly connected to electrodes in a highly reliable fashion is constructed to be mounted on a printed circuit board or substrate in a stable and reliable manner. At both ends of a core of the chip coil, there are provided electrodes having a multilayer structure including a high-conductivity layer made of Ag, Ag—Pd, or a similar material; a solder barrier layer made of Ni; and an easy-soldering layer made of Sn or solder. End portions of the electric wire are embedded in the easy-soldering layer so that the resultant electrode structure has a substantially flat surface. A thermo-compression process is performed so that the end portions of the electric wire are connected to the solder barrier layer via solid welding and to the easy-soldering layer via brazing.
