Power Metal Strip® Resistors, High Power (7 W), Low Value (Down to 0.001 Ω), Surface Mount

Applications

• Improved thermal management incorporated into design
• 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
• Sulfur resistance by construction that is unaffected by high sulfur environments
• Very low inductance (< 5 nH)
• Solid metal nickel-chrome or manganese- copper alloy resistive element with low TCR (< 20 ppm/°C)
• Low thermal EMF (< 3 µV/°C)
• AEC-Q200 qualified (1)
• Flame retardance test may not be applicable to some resistor technologies
• Qualified to AEC-Q200 rev. D
• The WSHM2818 is rated at 7 W with maximum surface temperature of 180 °C
• SMD Power Metal Strip Marking (www.vishay.com/doc?30327)
• 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
• Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
• Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page
• Maximum working voltage - the WSHM is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
• Typical TCR is positive, for more details contact factory
• Refer to table “Links to Related Documents” for TCR white paper
