The WSL2512R0500FEA from Vishay Dale is a 50mΩ (0.05Ω) ±1% Power Metal Strip current sense resistor in a 2512 (6432 metric) package rated at 1W. Part of Vishay’s industry-leading WSL series, this metal element resistor uses a solid metal alloy resistive element that provides an ultra-low ±75ppm/°C temperature coefficient and excellent long-term stability. The AEC-Q200 qualification, combined with anti-sulfur, moisture-resistant, and pulse-withstanding features, makes it suitable for demanding automotive and industrial applications. The 4-terminal (Kelvin) pad layout enables precise voltage measurement by separating the current path from the sense connections.

The WSL2512R0500FEA uses Vishay’s proprietary Power Metal Strip construction, where a solid metal alloy resistive element is welded to copper terminals. Unlike thick film or thin film resistors, the metal alloy element provides an inherently low and stable temperature coefficient (±75ppm/°C) because the alloy composition is precisely controlled during manufacturing. The 4-terminal (Kelvin) pad layout on the PCB separates the high-current path (through the outer pads) from the voltage sensing connections (inner pads), eliminating the measurement error caused by solder joint and PCB trace resistance. The all-welded construction provides excellent pulse withstanding capability, as the metal element can absorb transient energy without degradation.
