TDK Product Features
The capacitance of aluminum electrolytic capacitors is defined by the surface of the aluminum anode foil. This surface is maximized by special etching processes, giving these capacitors the highest volumetric capacitance of all capacitor technologies and thus an attractive cost per capacitance ratio. Hybrid Polymer Aluminum Electrolytic capacitors are defined by extremely low ESR and therefore highest ripple current density which is reached by a combination of a highly conductive polymer and a liquid electrolyte is used instead of a liquid electrolyte Typical applications for aluminum electrolytic capacitors are in frequency converters, wind power converters, solar inverters, professional power supplies and UPS, medical applications, professional photoflash units and a wide range of automotive applications. The TDK aluminum electrolytic capacitors feature outstanding ripple current capabilities and very long-term reliability. Design flexibility and engineering expertise allow TDK to offer custom specific solutions.
