NC550 precision resistors are used in almost all areas of electronics because of their low inherent noise. Switching, control and measurement applications are particularly popular. The metal film resistors have been continuously developed over the years and are one of the most widely used resistor series. They have a resistance range of 1 Ω...5 MΩ, a temperature coefficient of ±3ppm/°C and a power rating of up to 0.6 Watts at 40 °C. The resistors are optionally available in a low inductance version and pre-loaded @ 100 h nominal load.
