The RN73 series of ultra high stability precision chip resistors from Tyco Electronics has been extended to offer resistance tolerances down to 0.01%, making the devices up to 10 times more accurate than previously available models.
Based on nichrome thin film technology, the devices are produced with three sputtered layers of resistive metal film. This enables very stable high frequency performance to be achieved. Temperature Coefficient of Resistance (TCR) values down to 10 ppm/°C, and 5 ppm/°C for some case sizes, are available over a wide value range (5R1 - 470K) in the E96 and E24 value grids.
Accurate and uniform physical dimensions facilitate automatic placement of the RN73 devices. Pack quantities are very flexible ranging from a small volume 250 piece cut strip up to higher volume 1000, 5000 and 10 000 piece tape on reels. For applications requiring higher power, the RP73 series resistors offer increased power dissipation, higher temperature capabilities (up to +155 degrees Celsius) and increased operating voltages (200V DC) compared to the standard RN73 series.
