The CRM1206-FX-R820ELF is a high-power, thick film chip resistor specifically designed for current sensing applications. It features a precise resistance of 820 mΩ with a ±1% tolerance and a temperature coefficient of ±100 ppm/°C. This 1206-size component is rated for 0.5 watts at 70°C and can operate over a wide temperature range from -55°C to +155°C. Its low resistance and high power handling make it ideal for power supplies, stepper motor drives, and as a snubber resistor in flyback power supplies.
