Description
Precision alloy chip resistors can be used for current sensing in power modules, inverters, hybrid power systems, high-current automotive applications, etc., with an average weight of approximately 38g. This dataset includes major raw and auxiliary materials, energy inputs, atmospheric emissions, and waste from the production process; infrastructure such as manufacturing of production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory was compiled from multiple data sources; the consumption of raw and auxiliary materials required for the plating process was extrapolated and estimated based on the plating process of thick-film chip resistors. The production of precision alloy chip resistors involves processes such as raw material pretreatment, electron beam welding, stamping and forming, laser trimming, plastic encapsulation, laser marking, stamping and pelletizing, electroplating, and inspection.
