CRT1206-BY-1003ELF is a thin-film precision chip resistor from Bourns' CRT Series, designed for high-accuracy current sensing and precision circuit applications. The device features ultra-tight tolerance of ±0.25%, a temperature coefficient of resistance of ±25 PPM/°C, and a maximum working voltage of 200 V with a power rating of 1/4 watt at 70°C. It operates reliably across a wide temperature range of -55°C to +155°C and is RoHS compliant with tin-plated termination. The CRT1206 package measures 3.05 × 1.55 × 0.55 mm and supports resistance values from 4.7 O to 1 MO depending on tolerance grade. This resistor is ideal for medical equipment, precision instrumentation, automation systems, and navigation equipment where stable, accurate resistance values are critical.
