Procurement Notes

Verify the specific suffix codes against official datasheets to confirm tolerance and TCR specifications. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm RoHS3 compliance status for current regulatory requirements. Check manufacturer documentation for any recent packaging or material changes that may affect assembly processes.

Selection Notes

Select this component when high stability and low noise are critical in analog signal paths. The 0.1% tolerance and ±25ppm/°C TCR make it suitable for precision voltage dividers and reference circuits. Consider the axial package constraints during layout planning compared to surface-mount alternatives.

Part Context

This part belongs to the RNF series of general-purpose and precision metal film resistors from Stackpole Electronics. The series is designed for applications requiring reliable performance and safety certifications. The axial leaded format allows for through-hole mounting on standard printed circuit boards.

Replacement Considerations

Cross-reference with other ±0.1% tolerance 1/2W axial metal film resistors. Verify matching TCR values and physical dimensions for direct substitution. Ensure equivalent flame-retardant coating properties if safety certification is required.
