NOVELTY - The invention discloses encapsulation method for capacitor, which has the core connect with pin, encapsulates and secures the housing to the outer edge of the core, the housing is composed of the mixture of graphene, carbon nano tube, magnetic material, metal oxide and polymer composites. Accordingly, the invention provides great thermal conductivity, which enhances heat dissipation, but also has good tightness that can improve the efficiency of enduring the environmental humidity of the capacitor, reduces the volume and height of the capacitor in order to prevent electric leakage upon using, enhances absorbability of electromagnetic wave, and further reduces electromagnetic interference.
