Vishay Intertechnology Standard Thick Film Chip Resistors Combine Sulfur Resistance With Long Term Stability

MALVERN, Pa. - Feb. 11, 2026 - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of AEC-Q200 qualified standard thick film chip resistors. The RCA-SR e3 series combines proven sulfur resistance with long term stability in five compact case sizes for automotive, industrial, and telecommunications applications.

Designed for use in sulfur-containing environments, the resistors released today provide a sulfur withstand capability in accordance with ASTM B809-25, demonstrating a maximum resistance drift of 1 % after 1000 h at 60 °C. Competing devices are tested at the same temperature for shorter duration. In addition, the RCA-SR e3 series ensures high stability across challenging environmental conditions, with ΔR/R ≤ 1 % after 1000 h of rated power at 70 °C.

Available in 0201, 0402, 0603, 0805, and 1206 case sizes, the resistors provide power ratings up to 0.25 W and an operating voltage range from 30 V to 200 V. The devices offer a wide resistance range from 10 Ω up to 10 MΩ, with tolerances of ± 1 % and ± 5 % and TCR of ± 100 ppm/K and ± 200 ppm/K.

RoHS-compliant and halogen-free, RCA-SR e3 series resistors feature a protective coating designed for electrical, mechanical, and climatic protection. Suitable for automatic soldering using wave, reflow, or vapor phase, the devices' pure matte tin plating provides compatibility with lead (Pb)-free and lead-containing soldering processes.
