Additional Details:

The WSC000162R00FEK has a resistance value of 162 milliohms. The 'FEK' suffix indicates a specific tolerance and TCR rating. The four-terminal Kelvin connection is crucial for eliminating the effects of lead resistance, which can introduce significant errors in low-resistance current sensing applications. By sensing the voltage directly across the resistive element, the Kelvin connection ensures that the measured voltage accurately reflects the current flowing through the resistor.
