Power Metal Strip
®
Resistors,
Low Value (down to 0.001 ), Surface Mount
FEATURES
• Molded high temperature encapsulation
• Improved thermal management incorporated
into design
• Ideal for all types of current sensing, voltage
division and pulse applications including
switching and linear power supplies,
instrumentation, power amplifiers
• Proprietary processing technique produces
extremely low resistance values (down to
0.001 )
• All welded construction
• Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• Solderable terminations
• Very low inductance 0.5 nH to 5 nH
• Excellent frequency response to 50 MHz
• Low thermal EMF (< 3 μV/°C)
• Integral heat sink not utilized for resistance values less
than 0.0075
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
Note
* Lead (Pb)-containing terminations are not RoHS-compliant.
Exemptions may apply.
Notes
• Part marking: DALE, model, value, tolerance, date code.
