CRM2512-JW-2R0ELF is a high-power thick film chip resistor manufactured by Bourns, engineered for current sensing, power supplies, stepper motor drives, and snubber applications in flyback power supplies. The device delivers a 1 watt power rating at 70°C with an operating temperature range of -55°C to +155°C, supporting resistance values from 47 milliohms to 1 megohm with tolerance options of ±1% and ±5%. Key electrical characteristics include a maximum working voltage of 954 mV for low resistance values (47–910 milliohms) and 200 V for higher resistance ranges, a maximum rated current of 6 A, and insulation resistance exceeding 1000 megohms. The resistor features a temperature coefficient of ±100 ppm for most resistance ranges and is RoHS compliant, making it suitable for demanding power management and current-limiting applications where reliability and precision are essential.
