Conductive polymer hybrid aluminium electrolytic capacitors, or commonly known as hybrid capacitors, are categorized as electrolytic capacitors. They differ from ceramic capacitors in terms of structure, material, and basic principle. These capacitors are superior to ceramic capacitors in the following aspects: (1) large capacity, (2) stable temperature characteristics *1, (3) no need to take bias characteristics into consideration *1, and (4) no need for sound prevention measures *1. (*1: Ceramic capacitors exhibit inherent disadvantages)
