Patent ID: 8773844

Claim:
A decoupling device, comprising: a lead frame, comprising: a cathode terminal portion and at least two opposite anode terminal portions disposed at two ends of the cathode terminal portion, wherein the two anode terminal portions are electrically connected with each other through a conductive line, the cathode terminal portion and the anode terminal portions comprise a plurality of terminal structures, the terminal structures are arrayed adjacent to each other; and at least two capacitor unit assembly, each capacitor unit assembly comprising a plurality of capacitor elements connected with each other in parallel, wherein the capacitor elements are arrayed on the same plane and are disposed on the lead frame, and each of the capacitor elements comprises a cathode portion and an anode portion opposite to each other; cathode portions of the capacitor elements are electrically connected with the cathode terminal portion, anode portions of the capacitor elements are electrically connected with the anode terminal portion, and the anode portions and the cathode portions of the adjacent capacitor elements are arrayed alternately, the capacitor elements are electrically connected with each other with a conductive adhesive, and the multiple capacitor unit assemblies are arrayed in a stacked manner and connected with each other in parallel, wherein the anode portions of the capacitor elements that are vertically stacked extend in a same direction.
