RNF18FBD12R1

Overview

The RNF18FBD12R1 is a fixed metal film through-hole resistor manufactured by Stackpole Electronics Inc. It features an axial leaded package with a resistance value of 12.1 ohms and a tolerance of ±1%. The component has a power rating of 0.125W (1/8W) and operates within a temperature range of -55°C to +155°C. It exhibits a temperature coefficient of ±100ppm/°C and includes flame-retardant safety coating.

Feature Summary

• Constructed from metal film composition for stable electrical performance
• Features flame-retardant safety coating for enhanced operational security
• Designed for general purpose applications in electronic circuits

Applications

• General purpose electronic circuitry
• Through-hole PCB mounting
• Signal conditioning networks

Procurement Notes

Verify the specific suffix 'B' against official Stackpole documentation, as standard series typically use 'F'. Confirm RoHS3 compliance status and exact physical dimensions via the manufacturer datasheet before integration. Ensure the axial package fits the target board layout constraints.

Selection Notes

Select this component when a precise 12.1-ohm resistance is required with tight ±1% tolerance. The 1/8W power rating suits low-power signal paths. Verify that the axial form factor aligns with the assembly process and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the RNF series of precision metal film resistors. It shares the same physical footprint and electrical characteristics as other variants in the series, differing primarily in resistance value and tolerance coding. The axial design facilitates manual or automated through-hole insertion.

Replacement Considerations

Stackpole RNMF14FTD12R1 is listed as an upgrade alternative for similar resistance values within the product line.
