CR0201AFW-1000GAS is a sulfur-resistant, AEC-Q200 compliant chip resistor manufactured by Bourns using thick film technology. This 1 watt rated resistor (at 70°C) features a 1000 ohm resistance value with ±1% tolerance and operates over a temperature range of -55°C to +155°C, with zero load derating at +155°C. The device is RoHS compliant, halogen-free, and incorporates anti-sulfur tin-plated termination (AS version) to resist sulfur contamination per ASTM B-809 standards. It is commonly used in automotive and industrial applications where reliability under harsh environmental conditions, including sulfur exposure, is critical.
