RNF14BBD5K23

Overview

The RNF14BBD5K23 is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 5.23 kOhms with a tight tolerance of ±0.1%. Rated for 0.25W (1/4W) power dissipation, the component operates within a temperature range of -55°C to 155°C and exhibits a temperature coefficient of ±25ppm/°C. The physical dimensions are 0.093 inches in diameter by 0.250 inches in length (2.35mm x 6.35mm). It includes flame retardant coating and complies with RoHS3 standards.

Feature Summary

• Precision metal film construction ensures stable electrical performance and high accuracy.
• Flame retardant safety coating enhances operational security in electronic assemblies.
• Wide operating temperature range supports reliability across diverse environmental conditions.

Applications

• Precision measurement instrumentation circuits
• High-accuracy signal conditioning networks
• Medical device electronics requiring strict tolerance compliance

Procurement Notes

Verify the specific suffix 'BB' against official Stackpole documentation to confirm packaging type and availability status. Ensure the requested quantity aligns with manufacturer standard packaging requirements. Cross-reference the exact part number with current distributor listings to confirm lead times and stock levels before finalizing procurement orders.

Selection Notes

Select this component when circuit design requires ±0.1% tolerance and low thermal drift. The 0.25W rating suits general-purpose applications where space constraints allow axial leads. Consider the ±25ppm/°C coefficient for environments with significant temperature fluctuations compared to higher drift alternatives.

Part Context

This resistor belongs to the RNF series of precision metal film components from Stackpole Electronics. The series is characterized by tight tolerances and stability. The RNF14BBD5K23 specifically utilizes the 'BB' designation, which typically indicates a tape-and-reel packaging format distinct from bulk or tray options found in other series variants.

Replacement Considerations

Direct substitutes include RNF14BAE5K23 and RNF14BTE5K23 from Stackpole Electronics, which share identical electrical specifications. Alternative manufacturers such as Vishay Dale offer equivalent parts like the CMF555K2300BEEA series for cross-brand sourcing needs.
