RNF14FBD38R3

Overview

The RNF14FBD38R3 is a fixed axial leaded metal film resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 38.3 ohms with a tolerance of ±1%. The component has a power rating of 0.25W (1/4W) and a maximum working voltage of 250Vrms. It exhibits a temperature coefficient of resistance (TCR) of ±100ppm/°C. The physical dimensions are 2.35mm in diameter and 6.35mm in length, designed for through-hole mounting. The operating temperature range spans from -55°C to +155°C.

Feature Summary

• Precision metal film construction ensuring superior electrical stability and low noise performance.
• Standard flame-retardant coating provides enhanced safety and fire resistance characteristics.
• Designed for general-purpose applications with robust overload voltage capabilities.

Applications

• General purpose electronic circuits requiring stable resistance values
• Industrial control systems utilizing through-hole mounting technologies
• Consumer electronics assemblies demanding reliable passive components

Procurement Notes

Verify the specific suffix codes against official Stackpole documentation to confirm tolerance and TCR ratings. Ensure compatibility with automated insertion equipment if Panasert availability is required. Confirm RoHS compliance status for current production runs. Check for any recent PCN notifications regarding material or manufacturing changes before finalizing procurement plans.

Selection Notes

Select this component when a standard 1/4W axial resistor with 1% tolerance and 100ppm/°C TCR is required. Consider the RNMF series if space constraints necessitate a smaller mini-axial footprint while maintaining similar electrical characteristics. Verify that the 250V working voltage meets the circuit requirements.

Part Context

This part belongs to the RNF/RNMF series of general-purpose metal film resistors from Stackpole Electronics. The series is known for replacing older MP series resistors and offers halogen-free, REACH compliant options. The RNF designation indicates the standard axial size within the product family.
