TOKEN RE High Precision Low TCR Resistors High Precision Low TCR Resistors Token Ultra Precision Ten-Times More Accurate Preview The RE Series from Token Electronics is capped ultra precision metal-film resistors, as well as a complete selection of MIL-PRF-55182 and GJB244A-2001 quality standards. Token offers a low-cost alternative to traditional solutions for precision applications. The RE is available in a resistance range of 10Ω ~ 15MΩ with a precision tolerance of ±0.02% and a temperature coefficient of resistance (TCR) of ±5PPM/°C, although other tolerances and TCRs are available. The resistance element in these devices is a precisely controlled thin film of metal alloy deposited on a high quality alumina substrate. Plated caps are force-fitted before the assembly is trimmed using advanced laser techniques to ensure excellent performance and low electrical noise. Leads are welded to the end caps prior to the resistor being coated with epoxy. Products equate Vishay, Ohmite, Caddock, IRC, EBG, Panasonic Precision Devices with more competitive price and fast delivery. Detailed precision RE specifications, both mechanical and electrical, please contact our sales representative for more information.
