Current Sensor

Description

The Current Sensors are resistors used to detect the current in the circuit. It accurately calculate the current by measuring the voltage drop generated by the current flowing through the resistance with known resistance and using Ohm's Law (I = u / R). Generally, the resistance of current sensors is very small, between 1m Ω and 1 Ω, with high tolerance and low TCR. In highly precise applications, the resistance of pin and the contact resistance may be greater than the resistor itself. Therefore, if two-pin resistors are used, the error caused by pins may be serious. In order to eliminate the influence of voltage drop caused by pins (non resistance elements) and obtain extremely accurate current value, four-pin Kelvin structure resistor is recommended.
