The KOA RN73H and RN73R are thin film resistors designed for high
reliability in industrial, medical, transportation, and other high
temperature and high humidity applications. They have a protective
coating that improves moisture resistance stability to a 0.1% Delta R at
85% Relative Humidity and 85 Degree Celsius for 1000 hours.
The resistors can be used at temperatures up to 155 degrees and offer
exceptional thermal stability, with TCR as low as plus or minus 5 ppm
per degree C. Resistors are available from 10 ohms to 1.5 megaohms and
with standard tolerance down to 0.05 percent.
RN73R resistors offer an improved electrolytic corrosion resistance
compared to other RN73 resistors, while the RN73H series is AEC-Q200
qualified for automotive applications.
