RN73R – KOA with Enhanced Standard Thin-Film Series

The KOA standard thin-film series RN73 is evolving into RN73R. However, not only the designation changes, but several technical parameters are also significantly improved. For instance, derating within the rated ambient temperature range now begins at 85°C, compared to 70°C previously. Furthermore, long-term stability in the load life test (1000h) improves to ±0.1%, compared to ±0.25% before. The RN73R is also more moisture-resistant and less susceptible to overload than its predecessor.

Like the automotive version RN73H, the RN73R is available in sizes 0402 to 1210. The lowest resistance tolerance is specified as 0.05%, and the lowest TCR is 5 ppm/K. The RN73R is primarily suitable for industrial and medical technology applications, while the automotive type RN73H naturally meets the requirements according to AEC-Q200.
