Abstract
A low inductance capacitor with a concentric ring capacitor core similar to water ripple diffusion is provided, including a laminated bus bar, a capacitor core, a filler and a shell; where the laminated bus bar is embedded in a center of the capacitor core; and the filler is poured between the capacitor core and the shell. The capacitor features a concentric ring-shaped design. The capacitor core consists of metal electrode layers, insulating inner films, and a central gap hole, with the metal electrode layers arranged in a concentric pattern that decreases in thickness, mimicking the diffusion of water ripples.
