Power Resistor

KEVLIN - 5089-P - Current Sensor Resistor. 0.01-Ohm.

Current sense resistors are often referred to as 'shunt' resistors. Shunt resistors are used to monitor the amount of current that is flowing through a circuit. Such resistors have very low resistance values, typically less than 50 milli-ohms (0.050 ohms) and often lower.

A 'Kelvin' configuration resistor features four leads or terminations. These four terminal resistors enable current to be applied through two opposite leads and a sensing voltage to be measured across the other two leads. The Kelvin configuration effectively eliminates the resistance and temperature coefficient of the leads. The Kelvin connection can also simplify board design by incorporating all terminals for the sensing circuit into one part. A Kelvin connection is essential for accurate current sensing and simplified board design.

Vishay - S102C 50K000 - High Precision Foil Resistor, 50.000K Ohms (50,000) 0.01%

The S102C 50K000 0.01% is a through-hole Foil Resistor with Bulk Metal® foil (BMF) technology for applications that require high precision and high stability. BMF technology allows us to produce customer orientated products, designed to satisfy challenging and specific technical requirements. It offers low TCR, excellent load life stability, tight tolerance, fast response time, low current noise, low thermal EMF and low voltage coefficient, all in one resistor. The S series is virtually insensitive to destabilizing factors. The resistor element is a solid alloy that displays the desirable bulk properties of its parent material, thus it is inherently stable and noise free. The S series resistor is the modern generation of precision resistor. The standard design of this resistor provides unique combination of characteristics found in no other single resistor.
