The 7-1879128-4 is a thin film precision resistor from the RN73 series, designed for high-stability applications requiring excellent accuracy and temperature stability. It features a temperature coefficient of resistance (TCR) as low as 5 ppm/°C, tolerance down to 0.01%, and is manufactured using three sputtered nichrome layers for optimum performance. The resistor is available in multiple case sizes (0402 to 2512) with electroplated 100% matte tin terminal finish and MSL1 moisture sensitivity level rating. These precision resistors are ideal for communications, industrial controls, instrumentation, and medical applications where high accuracy and long-term stability are critical requirements.
