  • LC filter with external electrodes only on a smaller layer
    Patent number: 5777533
    Abstract: There is provided an LC filter in which the leakage of an electromagnetic field to the outside is suppressed. The LC filter 20 includes a laminated element 22. The laminated element 22 includes a multiplicity of dielectric layers 24a-24h. One end of a pattern electrode 34a serving as an inductor of an LC resonator is connected to a capacitor electrode 30a serving as a part of a capacitor of an LC resonator through a via hole formed in the dielectric layers 24d and 24e. The other end of the pattern electrode 34a is connected to one end of a pattern electrode 36a through a via hole formed in the dielectric layer 24f. The other end of the pattern electrode 36a is connected to a ground electrode 32a through a via hole formed in the dielectric layers 24e and 24f. Similarly, one end of a pattern electrode 34b serving as an inductor of another LC resonator is connected to a capacitor electrode 30b serving as a part of a capacitor of an LC resonator through a via hole formed in the dielectric layers 24d and 24e.
