The component has a power rating of 0.5W and operates within a temperature range of -55°C to +155°C. It utilizes an axial leaded package with dimensions of 2.35 mm diameter and 8.75 mm length. The device supports a maximum working voltage of 350V and exhibits a temperature coefficient of resistance (TCR) of 100 ppm/°C.

Feature Summary

• Precision metal film construction for superior electrical stability
• Flame-retardant coating for enhanced safety compliance
• Axial through-hole mounting for standard PCB integration

Applications

• General purpose electronic circuits
• Automotive grade applications requiring AEC-Q200 qualification
• Signal conditioning and measurement equipment

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct tolerance and packaging options. Confirm RoHS and REACH compliance status prior to procurement. Check manufacturer lead times as production cycles may vary. Ensure storage conditions align with moisture sensitivity requirements for axial components.

Selection Notes

Select this component when high precision and thermal stability are required in through-hole designs. The 1.82 MOhm value suits high-impedance signal paths. Consider the 0.5W power rating for moderate current applications. Verify spatial constraints for the axial footprint before finalizing the schematic design.

Part Context

This part belongs to the RNF series of general-purpose metal film resistors from Stackpole Electronics. The series is characterized by flame-proof coatings and Panasert availability. It serves as a reliable alternative to older carbon composition types, offering improved noise characteristics and long-term stability for industrial and automotive electronics.

Replacement Considerations

Direct substitutes include other 1.82 MOhm ±1% 0.5W axial metal film resistors from manufacturers such as Yageo or Vishay. Ensure equivalent TCR and voltage ratings are maintained. Verify that replacement parts meet the same environmental and safety certifications.
