Very High-Power (1 W), Low Value (Down to 0.001 Ω) ,
Surface-Mount Power Metal Strip® Resistor
Key Benefits
• 1 W power capability in very small 1206 package
• Saves space by enabling use of a 1206 size package to replace 1 W 1508 (35 % space savings), 2010 (61 % space savings) and 2512 (75 % space savings) size parts
• Very low resistance values of 1 mΩ to 50 mΩ
• Low TCR resistance element (< 20 ppm/°C) results in accurate current-sensing,
allowing the use of lower cost ICs
• Lead (Pb)-free construction is RoHS-compliant
APPLICATIONS
• Computer
• Automotive
