Selection Guide Between Aluminum Electrolytic and Ceramic Capacitors for Power Converters
the selection between aluminum electrolytic and ceramic capacitors is not about finding a superior technology, but about matching the component's strengths to the circuit's needs. Aluminum electrolytics are the workhorses for high-capacitance, high-voltage bulk storage, while MLCCs are the precision tools for high-frequency decoupling and stability. The most robust power converter designs intelligently leverage the complementary characteristics of both capacitor families to achieve optimal performance, reliability, and cost-effectiveness.
