An integrated capacitor assembly that offers improved performance characteristics in a convenient and space-saving package is provided. More specifically, the capacitor assembly contains a multi-anode stack of at least two electrolytic capacitors and at least one ceramic component, which are connected in parallel to common terminals within an encapsulating case. The resultant capacitor assembly is characterized by such performance characteristics as relatively high capacitance, low ESR, low piezoelectric noise, and space reduction. Reduced piezoelectric noise may be particularly advantageous for providing clear filtering in audio/video data processing and communication.
