Power Metal Strip® Current Sense Resistors, Low Value (0.3 mΩ to 3 mΩ), Surface-Mount, High Power

Applications

• Ideal for all types of current sensing and pulse applications including switching and linear power supplies, instruments, power amplifiers, shunts, power inverters, and battery management
• Proprietary processing technique produces low resistance values (0.3 mΩ to 3 mΩ)
• Solid metal manganese-copper and iron-chromium- aluminum alloy resistive element with low TCR (< 20 ppm/°C)
• Very low inductance 0.5 nH to 5 nH
• Low thermal EMF (< 3 μV/°C)
• Sulfur resistance by construction that is unaffected by high sulfur environments
• AEC-Q200 qualified rev. E
• Part marking: no part marking on these parts
• “ Thermal Management for Surface-Mount Devices” white paper: www.vishay.com/doc?30380
• See Fig. 1 - Ambient Temperature Derating
• See Fig. 2 - Terminal Temperature Derating
• Other values may be available, contact factory
• Consult factory for detailed TCR performance across full temperature range as performance is resistance value specific
• “Temperature Coefficient of Resistance for Current Sensing” white paper: www.vishay.com/doc?30405
• Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
• Element TCR - only applies to the alloy used for the resistor element
• Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
