Power Metal Strip^®Resistors, High Temperature (275 °C),

Low Value (Down to 0.01 Ω), Surface Mount

FEATURES

• Ideal for all types of current sensing, voltage

division and pulse applications including

switching and linear power supplies,

instruments and power amplifiers

• Proprietary processing technique produces

extremely low resistance values

• All welded construction of the Power Metal

Strip^®resistors are ideal for all types of current

sensing, voltage

applications

division

and

pulse

• Sulfur resistance by construction that is

unaffected by high sulfur environments

• Specially selected and stabilized materials allow for high

temperature derating (to +275 °C)

LINKS TO ADDITIONAL RESOURCES

• Solid metal nickel-chrome alloy resistive element with low

TCR (< 20 ppm/°C)

• Very low inductance (< 5 nH)

3D Models

Design Tools

• 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

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 WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
