CR0603-FX-1003ELF is a precision thin-film chip resistor designed for high-reliability applications requiring tight tolerance and stable performance across temperature variations. This 0603-sized component delivers a power rating of 0.10 W at 70°C with a maximum working voltage of 50 V and maximum overload voltage of 100 V. The resistor features a 1% tolerance with ±100 ppm/°C temperature coefficient, operating reliably over the temperature range of -55°C to +155°C. It incorporates a three-layer contacting process with nickel barrier to prevent leaching and ensure excellent solderability, making it suitable for all types of soldering processes including lead-free reflow. The device is RoHS compliant and commonly used in precision instrumentation, data acquisition systems, and industrial control circuits where accuracy and long-term stability are critical.
