Vishay Dale
Power Metal Strip® Resistors, Very High Power (to 15 W),
Low Value (Down to 0.0001 Ω), Surface-Mount
FEATURES
• 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
0.0001 Ω
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• Specially selected and stabilized materials
allow for high power rating (to 15 W)
• Very low inductance 0.5 nH to 5 nH
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified (1)
• Material categorization: for definitions of compliance
