    Abstract: A Non-Uniform Dielectric Layer, Multi-Layer-Ceramic-Capacitor (MLCC) has upper and lower dielectric layers separating upper and lower electrode layers, where the lower dielectric layers have a greater vertical thickness than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces on a printed circuit board (PCB) on which the capacitor is mounted. Such an MLCC may include an upper set of dielectric layers that separate adjacent pairs of upper electrode layers in a top portion of the MLCC, and a lower set of dielectric layers that separate adjacent pairs of lower electrode layers in a bottom portion of the MLCC. A bottom portion of the MLCC may be mounted on a PCB. The thickness of the lower dielectric layers may be between 1.5 and 3.5 times greater than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces in the audio range of human hearing.

    Abstract: A multi-layer capacitor such as a multi-layer-ceramic-capacitor (MLCC) has upper and lower dielectric layers separating upper and lower electrode layers, where the lower dielectric layers have a lower dielectric constant than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces on a printed circuit board (PCB) on which the capacitor is mounted. Such an MLCC may include the upper dielectric and electrode layers in a top portion of the MLCC; and the lower dielectric and electrode layers in a bottom portion of the MLCC. A bottom portion of the MLCC may be mounted on a PCB. As an example, the dielectric constant value of the lower dielectric layers may be between 1.5 and 3.5 times less than that of the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces in the audio range of human hearing. Other embodiments are also described and claimed.
