Vishay Launches RCA-SR e3 Resistors with ≤1% Drift After 1 000 h at 60 °C
Vishay Intertechnology launched RCA-SR e3 AEC-Q200 thick film chip resistors in five case sizes with power ratings up to 0.25 W and resistance from 10 Ω to 10 MΩ. The devices meet ASTM B809-25 sulfur resistance with ≤1 % drift after 1 000 h at 60 °C and ΔR/R ≤1 % after 1 000 h at 70 °C.
1. Product Introduction
Vishay Intertechnology introduced its RCA-SR e3 series of AEC-Q200 qualified thick film chip resistors, designed for automotive, industrial, and telecommunications applications. The lineup includes five compact case sizes from 0201 to 1206, supporting power ratings up to 0.25 W and resistance values spanning 10 Ω to 10 MΩ.
2. Sulfur Resistance and Stability
The RCA-SR e3 devices undergo ASTM B809-25 testing to demonstrate sulfur withstand capability, showing a maximum resistance drift of 1 % after 1 000 hours at 60 °C. They also maintain high stability with ΔR/R ≤1 % after 1 000 hours at 70 °C under rated power, outperforming competing parts tested for shorter durations.
3. Electrical Specifications
These resistors offer tolerances of ±1 % and ±5 %, TCR ratings of ±100 ppm/K and ±200 ppm/K, and operating voltages ranging from 30 V to 200 V. RoHS-compliant and halogen-free, they feature protective coatings and pure matte tin plating compatible with both lead-free and lead-containing solder processes.
4. Availability and Market Impact
Samples and production quantities are available immediately with a lead time of 12 weeks. This product launch strengthens Vishay’s passive component portfolio, potentially enhancing its position in markets requiring long-term stability in harsh environments.
