Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct tolerance and packaging specifications. Confirm that the required voltage rating and power derating curves align with the specific application environment. Check for RoHS compliance status and availability of EDA models for design integration prior to final procurement decisions.

Selection Notes

Select this component when high stability and tight tolerance are required in a compact 0805 footprint. The low temperature coefficient ensures minimal drift over wide thermal ranges. Ensure the circuit voltage does not exceed the 150V rating. Consider the 1/8W power dissipation limits under elevated ambient temperatures to maintain long-term reliability in dense PCB layouts.

Part Context

This resistor belongs to the RGC series from SEI Stackpole, designed specifically for high-reliability applications. The series emphasizes precision performance and automotive qualification. It serves as a surface-mount alternative to larger through-hole resistors where space constraints and thermal stability are critical design factors.

Replacement Considerations

Direct substitutes must match the 0805 package, 2.55MΩ resistance, ±0.5% tolerance, and 50ppm/°C temperature coefficient. Verify AEC-Q200 certification if automotive use is required. Cross-reference with other manufacturers' precision thick film resistor lines offering identical electrical parameters and physical dimensions.
