Sulfur-resistant thick film chip resistors for automotive and industrial applications

Vishay Intertechnology has released a new series of sulfur-resistant long side termination thick film chip resistors optimized for automotive and industrial applications. For high sulfur environments, resistors in the AEC-Q200-qualified Vishay Draloric RCALS e3 series feature a patented construction that provides a sulfur withstand ability in accordance with ASTM B80995, tested at an advanced level of 90C for 1,000 hours. The devices' wide terminals enable high power ratings up to 2W. The resistors are available in five compact case sizes to save space on densely packed PCBs: 0406, 0612, 1020, 1218, and 1225. The devices offer a resistance range from 1ohm up to 2.2Mohm with tolerances of ±1% and ±5%, TCR of ±100ppm/K and ±200ppm/K, and an operating voltage range from 50V to 200V. The resistors are RoHS-compliant and halogen-free.
