    Abstract: An LC filter includes first and second LC resonators including first and second inductors, respectively. In plan view from a winding axis direction of the first inductor, an air-core portion of the first inductor does not coincide with an air-core portion of the second inductor. The LC filter includes a bypass conductor that connects an intermediate portion of the first inductor between one end and another end of the first inductor and an intermediate portion of the second inductor between one end and another end of the second inductor.

    Abstract: An element mounting substrate includes a substrate, a first impedance element and a second impedance element on a main surface of the substrate and each having an electrode, and a transmission line on the substrate and having a first end connected to the electrode of the first impedance element and a second end connected to the electrode of the second impedance element. The first impedance element and the second impedance element are electrically connected in series via the transmission line on the substrate, and a line length between the first end and the second end in the transmission line is longer than a shortest distance between the first end and the second end.

    Abstract: A coil component includes a cover member containing an ultraviolet curable resin and a filler made of flat particles each having a major axis and a minor axis. The filler preferably contains talc particles. The particles of the filler contained in a portion of the cover member that covers a top surface of the flange are aligned to orient the major axes parallel or substantially parallel to the top surface. The filler contained in the portion of the cover member that covers the top surface has an area ratio of from 15.0% to 50.1% in a section of the cover member taken along a plane that passes through the central axis of a winding core portion and orthogonally intersects the top surface. The grain size of the particles of the filler in D50 is from 1 μm to 30 μm.

    Abstract: A balanced filter includes an unbalanced terminal, an unbalanced-side inductor, a first balanced terminal, a second balanced terminal, a balanced-side inductor, a power supply line, and a matching network. The unbalanced-side inductor is provided between the unbalanced terminal and a ground. The balanced-side inductor is provided between the first balanced terminal and the second balanced terminal and couples to the unbalanced-side inductor via an electromagnetic field. The power supply line includes a first end connected to a middle portion of the balanced-side inductor and a second end connected to a direct-current power supply. The matching network matches a first impedance between the first balanced terminal and the second end of the power supply line to a second impedance between the second balanced terminal and the second end of the power supply line.

    Abstract: An LC parallel resonator includes a plurality of dielectric layers stacked on top of one another, a capacitor electrode, and an inductor electrode. The inductor electrode defines a loop including a connection point, as a start point, connected to the capacitor electrode. The inductor electrode includes a first line electrode, first via electrodes, and second via electrodes. The first line electrode extends in a direction perpendicular or substantially perpendicular to a stacking direction of the dielectric layers. The first via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers, and connect the capacitor electrode to the first line electrode. The second via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers and are connected to the first line electrode.

    Abstract: In a wound inductor component, a first flange and a second flange are connected to both ends of a winding core in the central axial line direction, and protrude from the winding core to both sides in a height direction. A cover member covers a portion from the upper end of the first flange to the upper end of the winding core from above. In a sectional view including the central axial line and along the height direction, a first average distance, which is an average distance in the height direction from the upper end of the first flange to the upper end of the cover member, is 25% or more and 45% or less (i.e., 25% to 45%) of a second average distance, which is an average distance in the height direction from the upper end of the winding core to the upper end of the cover member.

    Abstract: An electronic component capable of obtaining higher attenuation characteristics. The electronic component includes a substrate, a first inductor and a second inductor disposed on a main surface of the substrate, and a transmission line provided on the substrate and connecting the first inductor and the second inductor in series. A first central axis of the first inductor and a second central axis of the second inductor are parallel to a main surface of the substrate and are not located on the same linear line when viewed from a direction orthogonal to the main surface of the substrate. The first inductor and the second inductor are arranged at a distance for magnetic coupling.
