Abstract: An inductor includes a core including a columnar shaft and a pair of supports on respective end portions of the shaft, a terminal electrode disposed on each support, and a wire wound around the shaft and having two end portions connected to the terminal electrodes, corresponding to the two end portions, on the supports. In the inductor, an impedance is approximately 500Ω or higher with respect to an input signal having a frequency of approximately 3.6 GHz.

Abstract: An inductor component comprises a core including a substantially column-shaped shaft and a support formed on an end portion of the shaft, and a terminal electrode formed on the support. The terminal electrode includes a side electrode section on a side face of the support and an end electrode section on an end face of the support. An end portion of the end electrode section adjacent to the side face is higher than an end portion of the side electrode section adjacent to the end face.

Abstract: An inductor includes a core including a columnar shaft and a support on an end portion of the shaft, a terminal electrode disposed on the support, and a wire wound around the shaft and having an end portion connected to the terminal electrode. The terminal electrode includes a bottom surface electrode on a bottom surface of the support and an end surface electrode on an end surface of the support. The end surface electrode includes an end portion in a width direction of the end surface and a central portion in the width direction of the end surface. The central portion is positioned higher than the end portion.

Abstract: An electronic component includes a core, a first outer electrode, a second outer electrode, one or more third outer electrodes, and a wire electrically connecting the first outer electrode, the third electrodes, and the second outer electrode in series in that order. The wire forms a first inductor by being wound on the core between the first outer electrode and one of the third electrodes, and also forms a second inductor by being wound on the core between one of the third outer electrodes and the second outer electrode.
