Precision chip resistors are ten times more accurate
The RN73 series of ultra-high-stability precision chip resistors from Tyco Electronics now offers resistance tolerances of 0.01 per cent. This makes the devices up to 10 times more accurate than previously available models.
Designed for telecommunication, industrial and military applications, RN73 series resistors are available in a choice of packages down to 0402 case size. The standard package size is 0805. Based on nichrome thin film technology, the devices are produced with three sputtered layers of resistive metal film. A very stable high-frequency performance can be achieved. Temperature coefficient of resistance values down to 10ppm/degC and even 5ppm/degC 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 resistors. 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. With a short standard lead time of four weeks, this makes RN73 series resistors a flexible fixed-precision SMD chip option.
For applications requiring higher power, the RP73 series resistors offer increased power dissipation, higher temperature capabilities (up to 155degC) and increased operating voltages (200V DC) in comparison with the standard RN73 series.
