Procurement Notes

Verify the specific suffix 'BD' against official Stackpole documentation to confirm the exact tolerance and packaging configuration, as distributor listings may vary. Ensure the requested quantity matches the manufacturer's standard reel or tube sizes. Confirm compliance requirements such as RoHS3 and REACH status prior to final procurement decisions.

Selection Notes

Select this component when high precision (±0.1%) and low temperature drift (±25ppm/°C) are required in a standard 1/4W axial package. It serves as a suitable replacement for older MP series resistors where tighter tolerances are necessary. Consider the operating temperature range and voltage ratings to ensure compatibility with the target circuit environment.

Part Context

This part belongs to the RNF/RNMF series of general-purpose metal film resistors from Stackpole Electronics. The series is characterized by precision performance and flame-retardant coatings. The RNF designation typically indicates a standard axial size, while the RNMF variant offers a miniaturized option for space-constrained applications.

Replacement Considerations

Stackpole documents indicate that the RNF 5% series replaces the MP series. For direct substitution, verify equivalent resistance and tolerance. Cross-reference with other manufacturers' axial metal film resistors rated for 0.25W and ±0.1% tolerance if supply chain constraints exist.
