RNF14FBD137R

Overview

The RNF14FBD137R is a fixed metal film resistor manufactured by Stackpole Electronics Inc. It features a 137 ohm resistance with a ±0.1% tolerance and a power rating of 0.25 W. The component operates within a temperature range of -55°C to +155°C and has a temperature coefficient of ±25 ppm/°C. It utilizes an axial through-hole package measuring 2.35 mm in diameter and 6.35 mm in length, compliant with RoHS standards.

Feature Summary

• Precision metal film construction ensures tight resistance tolerances for accurate circuit performance.
• Flameproof coating provides enhanced safety during operation under overload conditions.
• Low temperature coefficient maintains stable resistance values across wide thermal variations.

Applications

• Precision measurement instrumentation circuits
• High-accuracy signal conditioning networks
• Medical device electronic assemblies

Procurement Notes

Verify the specific suffix 'BD' against official Stackpole documentation to confirm the 0.1% tolerance and ±25 ppm/°C temperature coefficient parameters. Ensure the ordering part number matches the required axial leaded form factor and flameproof coating specifications before finalizing procurement orders.

Selection Notes

Select this component when designs require high precision stability in a standard axial footprint. The low temperature coefficient makes it suitable for applications where resistance drift must be minimized over varying environmental temperatures compared to standard general-purpose resistors.

Part Context

This resistor belongs to the RNF series of precision axial metal film resistors from Stackpole Electronics. The series is characterized by flameproof coatings and tight tolerances, distinguishing it from general-purpose carbon composition or standard metal film variants used in less critical applications.

Replacement Considerations

Direct substitutes include other Stackpole parts with matching 137 ohm value, 0.25W rating, and ±0.1% tolerance such as RNMF14FBD137R for miniaturized axial packages, provided the physical dimensions are compatible with the design constraints.
