A new series of sulphur-resistant long side termination thick film chip resistors optimised for automotive and industrial applications has been announced by Vishay Intertechnology. For high sulphur environments, resistors in the AEC-Q200-qualified Vishay Draloric RCA‑LS e3 series feature a patented construction that provides a sulphur withstand ability in accordance with ASTM B809‑95, tested at an advanced level of 90 °C for 1,000 hours.

The devices' wide terminals enable high power ratings up to 2.0 W.

RCA-LS e3 series 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 1 Ω up to 2.2 MΩ with tolerances of ± 1 % and ± 5 %, TCR of ± 100 ppm/K and ± 200 ppm/K, and an operating voltage range from 50 V to 200 V.

The resistors are RoHS-compliant and halogen-free.

Samples and production quantities of the RCA-LS e3 series are available now, with lead times of eight to 10 weeks.
