International ClassH01L 041/08Foreign Application Priority Data1984-10-17 JPAbstractAn electronic component comprises a plate-shaped element, electrodes being formed on both main surfaces of this plate-shaped element. A metal plate having nearly the same shape and nearly the same size as the element is provided for supporting one main surface of the element. The electrode on this surface of the element is connected to the metal plate, to which one lead terminal is connected. Further lead terminals are provided beside the element, having tips which are bent inside so as to face each other, and are connected to corresponding electrodes formed on the other main surface of the element. The metal plate reinforces and shields the plate-shaped element.Field of SearchPoint contact on major surfce onlyAdjustable Air gap Contact at edges only Clamped Spring bias Suspended by thin member With mounting or support means Piezoelectric slab having different resonant frequencies at different areas Combined with resonant structure More than two "U" or "tuning fork" shape Encapsulated or coated | |
