RNF14FBC187K

Overview

The RNF14FBC187K is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 187 kOhms with a tolerance of ±1%. The component has a power rating of 0.25W (1/4W) and operates within a temperature range of -55°C to +155°C. It exhibits a temperature coefficient of resistance (TCR) of ±50ppm/°C. The physical dimensions are 0.093 inches in diameter by 0.250 inches in length (2.35mm x 6.35mm). The device is RoHS compliant, lead-free, and halogen-free.

Feature Summary

• Precision metal film construction for superior electrical stability
• Standard flame-retardant coating for enhanced safety
• Suitable for Panasert automated assembly processes

Applications

• General purpose electronic circuits
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify the specific suffix against official datasheets to confirm tolerance and TCR specifications, as variations exist within the RNF series. Confirm packaging type availability, such as bulk or tape and reel, directly with the manufacturer or authorized distributors. Ensure compliance requirements match project standards, noting the component is RoHS3 and REACH compliant.

Selection Notes

Select this component when a standard 1/4W axial resistor with 1% tolerance and ±50ppm/°C stability is required. Consider the RNMF series if reduced physical size constraints apply to the design. Verify voltage ratings against circuit operating conditions to ensure safe operation within the specified limits.

Part Context

This part belongs to the RNF/RNMF series of general-purpose metal film resistors from Stackpole Electronics. The series is characterized by high reliability and precision. The RNF designation typically indicates the standard axial package size, while the RNMF variant offers a miniaturized form factor for space-constrained applications.

Replacement Considerations

Direct substitutes include other RNF14FBC variants with identical resistance values but different tolerances or coatings. Cross-reference with RNMF14FBC models if size reduction is permissible. Verify that alternative components meet the same ±50ppm/°C TCR and 155°C maximum operating temperature requirements.
