Ultra high precision chip resistors

Designed for telecommunication, 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 10 ppm/°C, and even 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 10000 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 +155 degrees Celsius) and increased operating voltages (200V DC) compared to the standard RN73 series.
