Abstract
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.
