RN73R Series High-Reliability Thin-Film Resistors

KOA’s thin-film chip resistors offer improved electrolytic corrosion resistance and high stability

Image of KOA's RN73R Series High Reliability Thin Film ResistorsKOA Speer Electronics’ RN73R series high-reliability thin-film resistors meet the demanding requirements of high heat and high moisture applications. The RN73R series provides improved electrolytic corrosion resistance and high stability compared to KOA’s existing RN73 thin-film resistors. The RN73R series offers excellent heat tolerance with an operating temperature range of -55°C to +155°C and a rated ambient temperature of +85°C, as well as improved moisture tolerance of 85% for 1,000 hours at +85°C. These resistors are ideal for applications that demand high reliability such as industrial devices, medical devices, gain adjustment resistors for op amp circuits, and dividers for power supply voltage monitors.
