Abstract:
    A surface mounted resonator having a cap means and a method of forming the same using an insulating ceramic substrate are provided, which can simplify a process of fabricating the surface mounted resonator. The surface mounted resonator includes: a cap means having upper and lower cap means, wherein the lower cap means has a vibration groove and the upper cap means has cap terminal connection electrodes; a resonance means disposed under the cap means and including upper, middle and lower resonance means, each of which has resonance electrodes and resonance holes disposed around the resonance electrodes; a condenser means having first to fifth condenser means sequentially stacked under the resonance means, wherein the first condenser means has another vibration groove, the second to fourth condenser means have condenser electrodes, and the fifth condenser means has condenser terminal connection electrodes; and connection wires for connecting the condenser terminal connection electrodes and the cap terminal connection electrodes.
