Metal Strip Technology: Unlike thick film resistors that use a ceramic-metal composite, the WSL series uses a solid metal nickel-chrome alloy resistive element. This provides much lower TCR (\u00b150 ppm\/\u00b0C vs \u00b1100-200 ppm\/\u00b0C) and better long-term stability.\n\n2. Low Inductance: The flat strip construction yields inductance below 5 nH, making it suitable for high-frequency switching applications like DC-DC converters.\n\n3. Kelvin Sensing: For the most accurate current measurement, 4-wire (Kelvin) sensing is recommended, connecting sense leads directly at the resistor terminations to eliminate lead resistance error.\n\n4. Power Derating: Full 1W up to 70\u00b0C, derating to zero at 170\u00b0C. The metal element provides excellent power handling compared to thick film alternatives.","pin_description":"\n

      Note: 2-terminal current sense resistor. For maximum accuracy, use 4-wire Kelvin connection with sense traces routed directly to the component pads. The 10 mOhm value provides 10 mV per ampere of current flow.<\/p>","application_scenarios":"\n
