✨ Product Features

Current Sensing & Shunt Application: These resistors are specifically designed for current sensing, where a low resistance value translates the current into a measurable voltage drop .
High Power in SMD Package: The 2512 package allows for a 1W power dissipation in a compact, surface-mount format suitable for automated assembly .
Low TCR: A low Temperature Coefficient of Resistance (around ±75 ppm/°C) ensures stable performance across a wide temperature range .
High-Temperature Operation: Designed to operate reliably at temperatures up to 170°C, making them suitable for demanding environments .
AEC-Q200 Qualified: Many parts in this category are qualified for automotive applications, indicating high reliability and rigorous testing .
Protective Features: Some models include features like anti-sulfur and moisture resistance, enhancing durability in harsh conditions .

Design Notes

Marking: The “R470” marking is a standard industry code for a 0.47Ω resistor.
Power Derating: For reliable operation above 70°C, the power rating must be derated according to the manufacturer’s curve.
