The CRM2512-FX-R680ELF is a high-power current sense chip resistor manufactured by Bourns using thick-film technology, designed for precision current sensing in power supplies, stepper motor drives, and snubber applications. This resistor features a resistance value of 0.68 ohms with ±1% tolerance (F grade) and a temperature coefficient of ±100 PPM/°C (X grade), operating reliably across a temperature range of -55°C to +155°C. The device is rated for 1 watt at 70°C with a maximum working voltage of 954 mV in the low-resistance range, and includes tin-plated (RoHS-compliant) termination for reliable soldering. Its robust construction and low resistance value make it ideal for high-accuracy current monitoring in power management circuits, industrial motor control systems, and power conversion applications where precise current measurement is critical.
