Power Metal Strip
®
Resistors, Very High Power (to 3 W),
Low Value (down to 0.0005
Ω),
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)
• All welded construction of the Power Metal
Strip
®
resistors are ideal for all types of current
sensing, voltage division and pulse
applications
• Proprietary processing technique produces
extremely low resistance values (down to
0.0005
Ω)
• Construction is impervious against high sulfur
environments (ASTM B 809-95 test method)
• Very low inductance 0.5 nH to 5 nH
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified
