Robot joint motors operate in confined spaces and involve high instantaneous currents. The original MLCC-based solution suffered from insufficient total capacitance, as well as significant heat genera

First, determine whether the available space can accommodate the required total capacitance and current-carrying capacity; then, evaluate the ESR, ripple current tolerance, and vibration resistance. For instance, you might consider the Yongming LKZ series (100V, 150μF, 8×25mm, coated aluminum-cased capacitors). Connecting four of these in parallel yields a nominal total capacitance of 600μF, with an ESR of approximately 0.20 Ω and a ripple current rating of 900 mA per unit. These specifications can serve as a basis for evaluating board-level filtering and transient energy storage; however, their suitability should be verified through actual testing and calculations at the system level.
