Multilayer Ceramic Capacitor Asymmetric Electrode Stress Distribution

The patent applies asymmetry by making the internal electrodes have different widths in the stacking direction. Specifically, adjacent internal electrodes are designed with different widths, creating an asymmetric structure that prevents stress concentration at electrode edges. This asymmetric design allows the capacitor to withstand higher voltages without cracking, as the stress is distributed more evenly throughout the dielectric layers rather than concentrating at sharp edges where electrodes of equal width meet.

The patent applies local quality by varying the width of internal electrodes at different positions in the stacking direction. Each internal electrode has a specific width tailored to its position, creating local variations in the electric field distribution and stress patterns. This local optimization ensures that areas prone to stress concentration have reduced electrode widths, while other areas maintain sufficient overlap area for high withstand voltage, thereby resolving the contradiction between reliability and strength.

The patent implements asymmetry by designing internal electrodes with different widths in the stacking direction, so that adjacent electrodes deliberately do not coincide. This asymmetric arrangement prevents the formation of stress concentration points that occur when electrodes of equal width align, while still maintaining sufficient overlap area for high capacitance and withstand voltage performance.

The patent applies parameter changes by systematically varying the width parameter of internal electrodes along the stacking direction. By changing the width parameter from one electrode to the next, the patent optimizes the balance between overlap area (affecting capacitance) and edge effects (affecting stress distribution), achieving both high withstand voltage and reduced stress concentration.

The patent applies local quality by optimizing the width of each internal electrode based on its specific position in the stacking direction. This local optimization ensures that sufficient overlap area is maintained in regions critical for capacitance, while electrode widths are reduced in regions where stress concentration would otherwise occur, thereby achieving both high capacitance and crack resistance simultaneously.

The patent uses asymmetry to break the periodic stress pattern that occurs with uniformly sized electrodes. By introducing asymmetric width variations, the patent maintains adequate overlap area for high capacitance while preventing the regular stress concentration that leads to cracking, thus resolving the contradiction between quantity of substance (capacitance) and strength (crack resistance).
