CRS2512AFX-47R0ELF is a high-power anti-surge resistor from Bourns' CRS-A Series, designed to provide robust surge protection in demanding applications. This thick-film resistor delivers a power rating of 2 W at 70 °C with a maximum working voltage of 300 V and maximum overload voltage of 600 V, enabling reliable performance under transient surge conditions. The device operates across a wide temperature range of -55 °C to +155 °C and features a sulfur-resistant design (ASTM B-809) with ±1 % or ±5 % resistance tolerance and temperature coefficient of ±100 PPM/°C to ±200 PPM/°C depending on resistance value. The resistor is RoHS compliant, halogen-free, and AEC-Q200 qualified, making it suitable for automotive and industrial applications. Common applications include power supply circuits and stepper motor drive protection, where high surge withstanding capability and thermal stability are essential.
