R100 2512 SMD Resistor (0.1 Ohm) – 1W High-Power Current Sensing Resistor

Overview 

The R100 2512 SMD Resistor is a low-resistance, high-power component specifically designed for current-sensing applications. The “R100” code indicates a resistance value of 0.1 Ohm (100 mΩ), and the “2512” package size (6.35mm x 3.18mm) is optimized for handling higher power dissipation compared to standard low-profile resistors. This component is a staple for engineers building shunt-based current monitoring circuits.

Key Features 

• Low Resistance: Precise 0.1 Ω value, perfect for shunt resistors in current measurement circuits.

• High Power Handling: Rated for 1W of power dissipation, allowing it to handle higher currents without overheating.

• Compact Form Factor: Standard 2512 metric package provides a balance between high power dissipation and space-saving PCB design.

• High Stability: Excellent thermal performance, ensuring reliable operation in power-intensive circuits.

Technical Specifications
