Abstract
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.
Claims24
A capacitor assembly comprising:
- a multi-anode stack comprising at least two electrolytic capacitors positioned adjacent to each other, the capacitors comprising a cathode termination and an anode termination formed by an anode wire;
- a ceramic component comprising a first polarity termination and a second polarity termination;
- a first lead frame portion to which the anode termination and the first polarity termination are electrically connected, wherein the first lead frame portion contains a first anode portion that defines a pocket for receiving the ceramic component;
- a second lead frame portion to which the cathode termination and the second polarity termination are electrically connected;
- and
- a case that encapsulates the electrolytic capacitors and the ceramic component, and leaves exposed respective portions of the first and second lead frame portions.
