The award-winning RN73 series resistors from Tyco Electronics is now available from TTI, Inc. Andy Kerr, TTI’s Product & Supplier Marketing Director, Europe, Discretes & Passives, said: “At TTI we pride ourselves on stocking the very best passives, discretes and connectors on the market, and we are now delighted to be able to offer our customers the RN73 series of ultra high stability precision chip resistors from Tyco Electronics. This range has been extended to offer resistance tolerances down to 0.01%, making 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, from 1206 down to 0402 case size. 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/ºC, and even 5ppm/ºC, are available over a wide value range (5R1 – 470K) in the E96 and E24 value grids.

Now, for applications requiring higher power, the RP73 series resistors offer increased power dissipation, higher temperature capabilities (up to +155ºC) and increased operating voltages (200V DC) compared to the standard RN73 series.Accurate and uniform physical dimensions facilitate automatic placement of the RN73 devices. Pack quantities are very flexible, ranging from a small volume 250 piece 7 inch reels up to higher volume 1000, 5000 and 10000 piece tape on reels. Together with a short standard manufacturing lead time of only four weeks this makes RN73 series devices the flexible fixed precision SMD chip resistor.

Kerr added: “TTI regards stock availability as of the utmost importance, and we strive to support design engineers with information which helps them achieve the optimum design and performance criteria. Internet newsletters, market reports and specific customer-orientated publications are free to download from our website at www.ttieurope.com.”
