DESIGN TOOLS (click logo to get started)
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
0.0002
• Construction is impervious against a high sulfur
environment (ASTM B 809-95 test method)
• Solid metal iron-chrome or manganese-copper
alloy resistive element with low TCR
(< 20 ppm/°C)
• 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
please see www.vishay.com/doc?99912
Notes
• 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
Note

Other values may be available, contact factory
Notes
(1)
Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
(2)
Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page
(3)
Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
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
