RNF14BBE158K

Overview

The RNF14BBE158K is a precision metal film through-hole resistor manufactured by Stackpole Electronics Inc. It features a nominal resistance of 158 kOhms with a tight tolerance of ±0.1%. Rated for 0.25W (1/4W) power dissipation, this axial component operates within a temperature range of -55°C to +155°C and exhibits a temperature coefficient of ±25ppm/°C. The device incorporates a flame-retardant coating for safety compliance and is available in tape and reel packaging.

Feature Summary

• Precision metal film construction ensures superior electrical stability and low temperature coefficient performance.
• Standard flame-retardant coating provides enhanced safety characteristics for circuit protection.
• Axial leaded package design facilitates reliable through-hole mounting on printed circuit boards.

Applications

• High-precision analog signal conditioning circuits
• Medical instrumentation requiring stable reference voltages
• Industrial control systems demanding long-term reliability

Procurement Notes

Verify the specific suffix 'BE' indicates the required ±0.1% tolerance and ±25ppm/°C TCR, as standard RNF series variants may differ. Confirm RoHS3 compliance status for your region. Ensure the axial package dimensions match your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when high accuracy and thermal stability are critical. The ±0.1% tolerance suits applications requiring precise voltage division or gain setting. Consider the ±25ppm/°C TCR for environments with significant temperature fluctuations compared to standard 100ppm/°C resistors.

Part Context

This part belongs to the RNF series of general-purpose precision metal film resistors from Stackpole Electronics. The series is designed to replace older MP series components while offering improved performance metrics. It is distinct from the RNMF mini-series and other tolerance variants within the broader resistor portfolio.

Replacement Considerations

Direct substitute: RNF14FTD158K (Note: Verify tolerance difference; F is typically ±1%, B is ±0.1%). Cross-reference datasheets for exact TCR and physical dimension compatibility before substitution.
