Vishay WSLF1206 5 W Power Metal Strip® Shunt: Higher Efficiency for AI Servers and Edge Systems

Compact 1206 package, 5 W power — built for AI and HPC power delivery

Vishay's new WSLF1206 Power Metal Strip® shunt resistor delivers up to 5 W in a 1206 surface-mount package. With resistance as low as 0.3 mΩ and TCR down to ±75 ppm/°C, it enables accurate current sensing with minimal power loss. Key benefits include high power density (>650 W/in²), low thermal EMF (<3 μV/°C), and ultralow inductance (<5 nH).

Why this matters for AI servers, GPUs, and edge devices

Modern AI systems prioritize power efficiency and tight voltage regulation. The WSLF1206 is ideal for VRMs, GPU power stages, data-center power distribution, and battery management in AI robots. Its low resistance reduces I²R losses, improving overall system efficiency and thermal headroom in dense racks and HPC nodes.

Designers gain space savings by avoiding parallel resistors. The device supports wide operating temperatures (-65 °C to +170 °C) and offers resistances from 0.3 mΩ to 3 mΩ with tolerances of ±1% to ±5%.

Applications and reliability

Typical uses: current sensing in switch-mode and linear PSUs, power amplifiers, inverters, UPS systems, motor drives, robotics, HVAC, and high-performance computing platforms. The WSLF1206 is RoHS-compliant, halogen-free, and sulfur-resistant for robust field performance.
