Cbureka Electronics High Power Low Resistance Sampling Resistor

The sampling resistor is a resistor used in the circuit to detect the size of the current. The way it works is by measuring the voltage drop produced after the current flows through a resistor of known resistance, and accurately calculates the current size based on Ohm's law (I=U/R). Usually the resistance of the sampling resistor is very small, between 1mΩ and 1Ω, with high accuracy and low temperature drift. In very precision applications, the resistance of the contact resistor and pins may be greater than the resistance of the resistor itself, so if a two-pin resistor is used, the error caused by the influence of the pins may be very large. In order to eliminate the influence of the voltage drop caused by the pins (non-resistive elements) and obtain extremely accurate current values, it is recommended to use a four-pin Kelvin structure resistor.
