Vishay Intertechnology Introduces New Series of Sulfur-Resistant Long Side Termination Thick Film Chip Resistors

Vishay Intertechnology, Inc. (NYSE: VSH) today 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 RCA LS e3 series feature a patented construction that provides a sulfur 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.

Device Specification Table:

Part # Case size Power rating P70(W) Operating voltage (V)
RCA0406-LS e3 0406 0.25 50
RCA0612-LS e3 0612 0.5 75
RCA1020-LS e3 1020 1.0 200
RCA1218-LS e3 1218 1.0 200
RCA1225-LS e3 1225 2.0(1) 200
(1) Specified power rating requires dedicated mounting conditions to achieve the required thermal resistance.
