Resistors,
Low Value (down to 0.001 ), Surface Mount
DESIGN TOOLS (click logo to get started)
FEATURES
• Molded high temperature encapsulation
• 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
0.001 )
• 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
(1)
• Material categorization: for definitions of compliance
please see
www.vishay.com/doc?99912
Notes
• This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details.
• Follow link to Overview of Automotive Grade Products for more details: www.vishay.com/doc?49924.
(1)
Flame retardance test may not be applicable to some resistor technologies.
Notes
• Part marking: DALE, model, value, tolerance, date code.
(1)
The WSR3 requires a minimum of 1050 sq. mil. circuit traces connecting to the recommended solder pad.
Note
(1)
Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes designating 1000 piece reels. These non-standard
packaging codes are identical to our standard EA (lead (Pb)-free) and TA (tin / lead), except that they have a package quantity of 1000 pieces.
