Estimation of Capacitance of Multi-Layer Ceramic Capacitors when Needle-Type Electrode Structure is Adopted

For a needle-type-electrode structure of multi-layer ceramic capacitors (MLCC), its capacitance was approximately estimated, based on the general definition of capacitance. The result of the estimation is given as a function of needle thickness, distance between the needle electrodes, and capacitor materials. Numerical estimation is extended to the 2 × 2 and 4 × 4 electrodes case. It is expected that needle-type-electrode structures will have advantages of high capacitance and a MLCC mass-production process. KCI Citation Count: 1
