Power Metal Strip® Resistors, Very High Power (to 3 W),
Low Value (down to 0.0005 ), Surface Mount
FEATURES
• Very high power to foot print size ratio (3 W in
2512, 2 W in 2010, 1 W in 1206, 0.5 W in 0805,
and 0.4 W in 0603 package)
• Ideal for all types of current sensing and pulse
applications including switching and linear
power supplies, instruments, power amplifiers
and shunts
• Proprietary processing technique produces
extremely low resistance values (down to
0.0005 )
• All welded construction
• Solid metal nickel-chrome or manganese-
copper alloy resistive element with low TCR
(< 20 ppm/°C)
• Very low inductance 0.5 nH to 5 nH
• Excellent frequency response to 50 MHz
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified available (1)
• Material categorization: for definitions of compliance
