• Industrial control systems

Procurement Notes

Verify the specific suffix against official Stackpole documentation to confirm tolerance and TCR ratings. Ensure the ordering code matches the required packaging format, such as bulk or tape and reel, as availability varies by configuration. Cross-reference the manufacturer part number with authorized distributor databases to confirm current production status and compliance certifications.

Selection Notes

Select this component when a standard 1/4W axial resistor with 1% tolerance and 50ppm/°C stability is required. The RNF series offers a reliable alternative to older MP series resistors. Consider the RNMF variant if space constraints necessitate a smaller physical footprint while maintaining similar electrical characteristics.

Part Context
