Standard thick film chip resistors combine sulfur resistance with long-term stability

Vishay Intertechnology, Inc. has 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 provide a sulfur withstand capability in accordance with ASTM B809-25, demonstrating a maximum resistance drift of 1% after 1000h at 60C. Competing devices are tested at the same temperature for a shorter duration. Also, the series ensures high stability across challenging environmental conditions, with ΔR/R ≤1% after 1000h of rated power at 70C.

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

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