    摘要： An LC resonating component, such as multilayered LC filter 1, is provided having a high Q-value and a low profile. The filter 1 comprises an insulating sheet 2 having a ground electrode 3 on its surface and in its center a via hole 7 connected to the ground electrode 3, an insulating sheet 2 having a via hole 4 in its center, insulating sheets 2, 2 having capacitor electrodes 5, 6 on their respective surfaces, and a protective insulating sheet 2. The via hole 7 is connected to the via hole 4, wherein the via holes 4 and 7 together comprise an inductor conductive body 8. The inductor conductive body 8 is perpendicular to the planes defined by capacitor electrodes 5, 6, and thus the magnetic flux created around the inductor conductive body 8 does not penetrate the capacitor electrodes 5, 6.

    摘要： An LC resonant device effectively limits radiated noise and provides a high Q-value. In one embodiment, the LC resonant device comprises a laminated LC filter formed of: two insulating sheets having a first ground electrode and a second ground electrode formed on their respective surfaces; an insulating sheet having a third ground electrode on its surface and having a through hole formed in its central portion and connected to the third ground electrode; at least one insulating sheet having a through hole formed in its central portion; two insulating sheets having first and second capacitor electrodes on their surfaces respectively; and a cover insulating sheet. The through holes form an inductive conductor perpendicular to the capacitor electrodes. At least, one of the three ground electrodes is connected directly to the inductive conductor and the other ground electrodes are not directly connected to the inductive conductor.

    摘要： A multi-layered LC filter includes a plurality of insulating sheets stacked on each other and inductor via holes that are connected to each other in a stacking direction of insulating sheets, forming two columnar inductors. First ends of the inductors are connected to external ground electrodes via internal ground patterns, respectively. The external ground electrodes are electrically connected via a bridge pattern disposed in proximity to the inductors, allowing adjustment of the value of the magnetic coupling between LC resonators without changing the size of the filter.

    摘要： A multilayer LC composite component minimizes the inductances of ground patterns to prevent electromagnetic waves from leaking outside the component. The multilayer LC composite component includes ground patterns having large areas arranged in the upper and lower sections of the component, with inductor patterns and resonant capacitor patterns arranged between the ground patterns. The ground patterns have portions extended in different positions such that no clearance is left between the extended portions in plan view.
