Capacitor lead pins are fixed conductive pins inside capacitors, connecting to the capacitor's conductive plates and enabling the formation of capacitance between internal conductors. The average diameter of the lead wire is 1.4 cm, with an average weight of approximately 0.05 g. This dataset includes major raw materials, auxiliary materials, energy inputs, and waste outputs from the production process; infrastructure such as manufacturing of production equipment and facility construction is not within the system boundary. The life cycle inventory is compiled from data sourced from multiple references. The production process of capacitor lead pins includes mechanical stamping, inspection, cleaning, dehydration, drying, and formation.
