The RT0603BRD073K09L is a surface-mount technology thin film resistor, manufactured by Yageo. It has a power rating of 1/10 watt, a resistance of 3.09K-ohms, a tolerance of 0.1%, and a temperature coefficient of 25 parts-per-million (ppm/°C). It is a “chip” style component, with dimensions of only 0.06” by 0.03”, and features a flat termination for easier SMT soldering processes. It has a wide temperature range of -55 to +125°C, giving it excellent performance characteristics when used in high-temperature or normal environment. The flat termination of the component allow for easier polarization and polarity identification, as well as allows contact with other adjacent components for good electrical connections and stability.
