The capacitor conductive needle is a conductive needle fixed inside the capacitor, used to connect with the capacitor's conductive plate, serving to form capacitance between conductors inside the capacitor. The average diameter of this needle is 1.4cm, and the average weight is approximately 0.05g; this data set includes primary raw materials, energy, and waste from the production process but does not include the manufacturing of production equipment, construction of factory buildings, and other infrastructure within the data set boundary; the data inventory was formed by merging data from multiple sources; the production of the capacitor needle includes mechanical stamneedleg, inspection, cleaning, dehydration, drying, and aging.
