RNF14FBD154R

Overview

The RNF14FBD154R 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 154 ohms, a power rating of 0.25W (1/4W), and a tolerance of ±0.1%. It operates within a temperature range of -55°C to +155°C and exhibits a temperature coefficient of resistance (TCR) of ±25ppm/°C. The device is RoHS compliant and lead-free.

Feature Summary

• Precision metal film construction for superior electrical stability
• Standard flame-retardant coating for safety compliance
• Low temperature coefficient of resistance for high accuracy

Applications

• High-precision analog signal conditioning circuits
• Medical instrumentation requiring stable reference voltages
• Test and measurement equipment calibration networks

Procurement Notes

Verify the specific suffix 'BD' indicates the ±0.1% tolerance and ±25ppm/°C TCR configuration against the official Stackpole datasheet. Confirm that the axial leaded form factor matches the target PCB layout requirements. Ensure the operating voltage does not exceed the maximum rated working voltage for the 0.25W package size during procurement validation.

Selection Notes

Select this component when circuit design demands tight resistance tolerance and low thermal drift. The ±0.1% tolerance ensures minimal deviation in critical gain or attenuation stages. The ±25ppm/°C TCR provides stability across wide temperature variations compared to standard 1% resistors. Verify availability of the specific precision grade as it differs from standard commercial grades.

Part Context

This part belongs to the RNF series of general-purpose metal film resistors from Stackpole Electronics. The RNF series is designed to replace older carbon composition types while offering better performance. The '14' code denotes the physical size class corresponding to the 1/4W power rating and axial package dimensions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent precision resistors from other manufacturers based on matching tolerance, TCR, and physical dimensions.
