With \u00b11% tolerance and low TCR, it provides accurate voltage drop measurement proportional to load current. The 0.5W power rating supports continuous currents up to approximately 1.67A. AEC-Q200 qualified for automotive applications, it operates from -55\u00b0C to +155\u00b0C.","working_principle":"As a current sense resistor, the RL1210FR-070R18L is placed in series with the load current path. By Ohm's law, the voltage drop across the resistor (V = I \u00d7 R = I \u00d7 0.18) is directly proportional to the current. An amplifier or ADC measures this small voltage to determine current magnitude. The low 0.18\u03a9 value minimizes power dissipation (P = I\u00b2 \u00d7 R) while still providing a measurable voltage signal. The \u00b11% tolerance ensures measurement accuracy across production.","pin_description":"
