摘要： A piezoelectric component includes leads and being arranged to suppress the adhesion of solder or a conductive adhesive agent to lead-out electrodes or vibration electrodes thereof, which is therefore resistant to the deterioration of electrical characteristics such as resonance characteristics, and which minimizes fluctuation of the electrical characteristics. In this piezoelectric component having the leads, the vibration electrodes are provided on each of the first and second main surfaces of a piezoelectric plate, and each of the vibrating electrodes is connected to a terminal electrode via a lead-out electrode. Each of the holding portions of a lead terminal is bonded to the terminal electrode, and is arranged so as not to extend onto the lead-out electrode.

摘要： Improved bandwidths and oscillation uniformity is obtained through a rod type BAW TFR structure formed over a semiconductor support. The resonator includes a first and a second electrode and a plurality of distinct elemental piezoelectric structures between the electrodes. Each of the piezoelectric structures has a length, a width and a height, the height being the distance between the electrodes. The height of the piezoelectric structures is at least equal to or more than one of the length or the width, or both. Such resonator is made by forming on a common bottom a plurality of distinct piezoelectric structures each having a length, a width and a height, wherein the height is formed at least equal to the width or the length of the piezoelectric structure, and forming a common top electrode thereover.

摘要： A thickness-extensional piezoelectric resonator using a harmonic of a thickness-extensional vibration mode has a compact size, large electric capacity, is not affected by the stray capacitance of a circuit board, and has small variations in resonance characteristics. The thickness-extensional piezoelectric resonator includes a piezoelectric body, a first excitation electrode, a second excitation electrode, a terminal electrode and a connection electrode disposed on outer surfaces of the piezoelectric body, as well as an internal electrode inside of the piezoelectric body. Portions where the first excitation electrode, the second excitation electrode and the internal electrode overlap define a resonating portion. In the length direction of the piezoelectric body, a vibration-attenuating portion is defined at opposite sides of the resonating portion, whereas in the width direction, the vibration-attenuating portion is not provided at each side thereof. In addition, a relationship of Go/D≧2.0 is satisfied, wherein Go represents a distance between the terminal electrode and the first excitation electrode, D is substantially equal to T/N, and wherein T is the thickness of the piezoelectric body and N is the order of harmonic vibrations.

摘要： First resonant electrodes are provided on one main surface of a piezoelectric plate, a second resonant electrode is provided on the other main surface of the piezoelectric plate, such that the first and second resonant electrodes face each other. An energy trap-type piezoelectric vibrating section is thus provided by the first and second resonant electrodes, and a capacitor section is provided in a position separated from the vibrating section. The capacitor section has a first capacitor electrode provided on the upper surface of the piezoelectric plate, and has a second capacitor electrode provided on the bottom surface of the piezoelectric plate. Further, an outer edge portion of the first capacitor electrode is spaced from an outside edge of the piezoelectric plate, thus providing a margin area except at the portions led out to the outside edge of the piezoelectric plate.

Such resonators may be coupled together to form filters or other frequency selective devices. The bulk acoustical wave filter is constructed from a piezoelectric (PZ) material having a first surface and a second surface and first and second electrodes. The first electrode includes an electrically conducting layer on the first surface, and the second electrode includes an electrically conducting layer on the second surface. The first electrode overlies at least a portion of the second electrode, the portion of the first electrode that overlies the second electrode has a periphery which is a non-rectangular, irregular polygon. In the preferred embodiment of the present invention, the periphery is a three-sided, four-sided, or n-sided irregular polygon in which no two sides are parallel to one another.

The resonator includes a piezoelectric substrate laminated with dielectric substrates and external electrodes disposed on the laminate body. A plurality of external electrodes are arranged to extend from the outer major surface of the first dielectric substrate to the outer major surface of the second dielectric substrate along first and second side surfaces disposed opposite to each other. On the outer major surface of the second dielectric substrate, at least one external electrode is divided into first and second electrode portions.
