CRM2512-FX-R500ELF is a high-power current sense chip resistor manufactured by Bourns using thick-film technology, designed for precision current sensing applications in power supplies and motor drives. The device features a 0.5 W power rating at 70°C, a resistance value of 0.5 ohms with ±1% tolerance, and a temperature coefficient of ±100 PPM/°C. It operates over an ambient temperature range of -55°C to +155°C with maximum working voltage of 675 mV for the 0.5 ohm resistance range, and maintains insulation resistance greater than 1000 megohms. The resistor is RoHS compliant with tin-plated termination, making it suitable for current sensing in power supplies, stepper motor drives, and as snubber resistors in flyback power supply applications where reliable performance and low resistance values are critical.
