The AR05FTCW1001 is a high precision, low temperature coefficient of resistance (TCR) surface-mount resistor manufactured by Viking. It is designed to provide electrical resistance with a highly precise ±0.5% tolerance and a low TCR of ±50 ppm/°C. It is designed to fit onto standard 0805 boards with a size of 2.0mm x 1.25mm. The resistor is RoHS compliant, meaning it is free from dangerous materials such as lead, mercury, hexavalent chromium and brominated flame retardants. It is suitable for a range of applications, including telecommunications, computers, instrumentation, medical equipment and lighting controls.
