Decoupling device

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 comprises a spacing, and the conductive line is disposed in the spacing;
• an insulating layer, disposed above the conductive line, wherein the insulating layer enables the cathode terminal portion and the anode terminal portions to be electrically insulated from each other;
• at least one capacitor unit assembly, comprising a plurality of capacitor elements in a manner of N pieces as one group and is electrically connected with each other in parallel, wherein N is an even number, the capacitor elements with N pieces 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 almost cover all area of the cathode terminal portion and are disposed on the insulating layer, and the cathode portions of the capacitor elements are electrically connected with the cathode terminal portion,
• anode portions of the capacitor elements are disposed on the anode terminal portion, and the anode portions of the capacitor elements are electrically connected with the anode terminal portion in parallel.
