Rated at 3W with low TCR of +\/-50 ppm\/C, AEC-Q200 qualified. The ultra-low 3mOhm resistance enables accurate current sensing at tens of amperes with minimal power loss, making it ideal for automotive battery management, motor drives, and power supply current monitoring.","working_principle":"The VSML2512S3-R003F operates as a precision current sense resistor:\n\n1. Metal Strip Construction: A solid metal alloy strip (manganese-copper or nickel-chromium) provides the resistive element. Unlike thick film, the metal strip has very low and predictable TCR (+\/-50 ppm\/C) and no aging effect.\n\n2. Kelvin Sensing: The 4-terminal construction (2 current + 2 sense) enables Kelvin (4-wire) measurement, eliminating lead resistance from the measurement. This is critical at 3mOhm where lead resistance would otherwise be a significant error source.\n\n3. Low TCR: +\/-50 ppm\/C means the resistance changes at most 0.005% per degree C. Over a 100C range, total drift is only +\/-0.5%, preserving the 1% tolerance budget.\n\n4. High Current: At 3mOhm, 30A produces only 90mV drop and 2.7W dissipation. The 2512 package provides sufficient thermal mass for 3W continuous dissipation.\n\n5. AEC-Q200: Automotive qualified for reliable current sensing in battery management and motor control applications.","pin_description":"\n
