Ceramic electronic component and method for manufacturing the same
A ceramic electronic component has a ceramic element assembly, external electrodes, and metal terminals. The external electrodes are arranged on the surface of the ceramic element assembly. The external electrodes contain a sintered metal. The metal terminals are electrically connected to the external electrodes, respectively. The external electrode and the metal terminal are directly diffusion-bonded by diffusion of metal in the metal terminals into the external electrodes. The above arrangement provides a ceramic electronic component having highly reliable metal particle bonding and a method for manufacturing the same.
Acoustically quiet capacitors
The described embodiments relate generally to printed circuit boards (PCBs) including a capacitor and more specifically to designs for mechanically isolating the capacitor from the PCB to reduce an acoustic noise produced when the capacitor imparts a piezoelectric force on the PCB. Conductive features can be mechanically and electrically coupled to electrodes located on two ends of the capacitor. The conductive features can be placed in corners where the amplitude of vibrations created by the piezoelectric forces is relatively small. The conductive features can then be soldered to a land pattern on the PCB to form a mechanical and electrical connection while reducing an amount of vibrational energy transferred from the capacitor to the PCB.
