The inside of the carton is separated into independent compartments with pearl cotton and corrugated partitions, and the individual protected capacitors are embedded one by one to prevent collisions with each other during transportation, buffer the impact of external forces, and prevent shell deformation, pin bending, and terminal damage. The exterior is sealed with tape, wrapped around the packing tape, and some export products will be covered with moisture-resistant film + Wooden packaging box to isolate moisture, dust, and static electricity, avoid capacitance oxidation or electrical performance damage, and improve the protection level of long-distance transportation.
