Which capacitor is better app or mpp and why?

Answer 1

The choice between an aluminum electrolytic capacitor (app) and a metalized polypropylene capacitor (mpp) depends on the application. MPP capacitors are generally better for high-frequency applications due to their lower equivalent series resistance (ESR) and better stability over temperature and frequency. They also have a longer lifespan and are less prone to failure than aluminum electrolytics. However, for applications requiring high capacitance at a lower cost, aluminum electrolytics may be more suitable.
