RNMF12FBD294K

Overview

The RNMF12FBD294K is a fixed metal film resistor manufactured by Stackpole Electronics Inc. It features an axial through-hole package with dimensions of 0.093 inches in diameter and 0.250 inches in length (2.35mm x 6.35mm). The component has a resistance value of 294 kOhms, a power rating of 0.5W (1/2W), and a tolerance of ±1%. It operates within a temperature range of -55°C to +155°C and exhibits a temperature coefficient of resistance (TCR) of ±100ppm/°C.

Feature Summary

• Constructed with precision metal film technology for stable electrical performance.
• Features standard flame-retardant coatings for enhanced safety.
• Designed as a miniaturized option suitable for applications with size constraints.

Applications

• General purpose electronic circuits requiring axial mounting
• Applications necessitating flame-retardant safety standards
• Designs with limited board space utilizing miniaturized components

Procurement Notes

Verify the specific suffix codes against official Stackpole documentation to confirm exact tolerance and TCR specifications. Ensure the ordering information matches the required axial lead configuration and power rating. Confirm RoHS compliance status directly from the manufacturer's current datasheet before procurement.

Selection Notes

Select this component when a 0.5W axial metal film resistor with 1% tolerance is required. Consider the ±100ppm/°C temperature coefficient for thermal stability needs. Verify that the physical dimensions fit the available axial footprint and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the RNF/RNMF series of general-purpose metal film resistors produced by Stackpole Electronics. The RNMF designation typically indicates a miniaturized version within this family, offering reduced physical size compared to standard RNF counterparts while maintaining similar electrical characteristics and safety features.

Replacement Considerations

Consult official Stackpole cross-reference lists for verified substitutes. Generic replacements must match the 0.5W power rating, 294k Ohm resistance, ±1% tolerance, and axial package dimensions to ensure functional compatibility.
