The KOA industrial standard Thin Film series RN73 becomes RN73R. But not only the designation changes, some technical parameters also improve significantly. For example, derating in the context of Rated Ambient Temperature only starts at 85°C, compared to 70°C before. Furthermore the long-term stability during the Load Life Test (1000h) improves to ±0.1%, compared to ±0.25% before. The RN73R is also more moisture resistant and less sensitive to overload than its forerunner.
Like the automotive version RN73H, the RN73R is available in sizes 0402 to 1210. The lowest resistance tolerance is specified as 0.05%, the lowest TCR is specified as 5 ppm/K. The RN73R is especially suitable for industrial and medical applications, the automotive type RN73H of course meets the requirements of AEC-Q200.
