The capacitor lead is a conductive needle fixed inside the capacitor, used to connect with the capacitor's conductive plates, serving the function of forming capacitance between the internal conductors of the capacitor. The average diameter of this lead is 1.4cm, with an average weight of approximately 0.05g; this dataset includes primary raw materials, energy, and waste generated during the production process, while the manufacturing of production equipment, and infrastructure construction such as plant buildings are not included within the dataset boundary; the data inventory is aggregated through multiple sources of data; the production of the capacitor lead involves processes such as mechanical stamneedleg, inspection, cleaning, dehydration, drying, and forming.
