RNF14CBD1K15

Overview

The RNF14CBD1K15 is a metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 1.15 kOhms with a tolerance of ±0.25%. 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 ±100ppm/°C and includes flame retardant safety coating.

Feature Summary

• Metal film construction for stable electrical performance
• Flame retardant safety coating for enhanced protection
• Wide operating temperature range suitable for demanding environments

Applications

• Precision analog signal conditioning circuits
• High-reliability industrial control systems
• Medical instrumentation requiring stable resistance values

Procurement Notes

Verify the specific suffix CBD indicates the 0.25% tolerance and 100ppm/°C coefficient, as these differ from standard RNF variants. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributor documentation prior to final procurement decisions.

Selection Notes

Select this component when precise resistance stability is required under thermal stress. The 0.25% tolerance offers higher accuracy than standard 1% parts. Ensure the axial package fits the PCB layout constraints and that the 1/4W power rating suffices for the circuit's dissipation requirements.

Part Context

This part belongs to the RNF series of precision metal film resistors. It shares the same physical dimensions and general construction as other RNF models but differs in electrical specifications such as tolerance and temperature coefficient. It serves as a high-precision alternative to lower-tolerance general-purpose resistors.

Replacement Considerations

Direct substitutes must match the 1.15k resistance, ±0.25% tolerance, and 100ppm/TC. Generic 1% tolerance resistors are not equivalent. Verify lead compatibility and voltage ratings against original design specifications before substitution.
