The all-welded construction of a solid nickel-chrome or manganese-copper alloy resistive element to copper terminals provides excellent long-term stability and very low inductance (0.5 to 5 nH). The +\/-1% tolerance and +\/-75 ppm\/degC TCR ensure accurate current measurement over temperature. AEC-Q200 qualified and inherently anti-sulfur, it is suitable for automotive and industrial applications.","working_principle":"The WSL2010R0200FEA operates as a four-terminal current sense resistor where the voltage drop across the 20 mOhm resistance is proportional to the current flowing through it (V = I x R). The solid metal alloy resistive element provides a stable, low TCR resistance value. The all-welded construction between the resistive element and the copper terminals eliminates contact resistance variability found in soldered or crimped connections. The very low inductance (0.5 to 5 nH) ensures accurate high-frequency current measurement without reactive errors. The low thermal EMF of less than 3 uV\/degC prevents DC offset errors in precision measurement circuits.","pin_description":"
