TE Connectivity are proud to introduce this ultra-high precision thin film
chip resistor, sister to our successful RN73 series. With tolerances from
0.01% to 0.1% and TCRs of ±2PPM and ±3PPM this takes the chip
resistor into new areas of stability and precision. Available on tape and
reel for automatic insertion processes, the RU73 is available in 7 case
sizes, with a higher power version available for 0603 to 2010 sizes
