Through using a combination of conductive polymer electric materials and liquid electrolytes as electrolyte, conductive polymer hybrid aluminium electrolytic capacitors merge the best of both worlds. The polymer enables low ESR as well as high ripple current characteristics, whereas the liquid electrolytes enable low leakage current and short circuit prevention. In addition, the capacitors can withstand high voltages and provide higher capacitance ratings. These features enable the polymer hybrid capacitors to have significant advantages over conventional tantalum, polymer, electrolytic, and multi layer ceramic chip capacitors. Conductive polymer hybrid capacitors can be used for a variety of applications, such as medical devices or communication repeaters (5G). In addition, the capacitors are especially suitable for applications in the automotive industry.
