Chip resistors are ten-times more accurate

Ultra-high-stability precision chip resistors are now available with resistance tolerances down to 0.01%.

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 10x more accurate than previously available models.

Designed for telecomms, industrial and military applications, RN73 series resistors are available in a choice of packages, down to 0402 case size.

Standard package size is 0805.

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 10ppm/C, and even 5ppm/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.

Together with a short standard lead time of only four weeks this makes RN73 series devices the flexible fixed precision SMD chip resistor.

Now, for applications requiring higher power, the RP73 series resistors offer increased power dissipation, higher temperature capabilities (up to +155C) and increased operating voltages (200V DC) compared with the standard RN73 series.
