RNF14FBD17R8

Overview

The RNF14FBD17R8 is a 17.8 Ohm resistor from Stackpole Electronics, featuring a 1/4W power rating and a ±1% tolerance. It utilizes a carbon film composition housed in an axial leaded package with dimensions of 0.035 x 0.098 inches. The component operates within a temperature range of -55°C to +155°C and exhibits a temperature coefficient of resistance (TCR) of ±200 ppm/°C. It meets RoHS standards and offers high stability with low noise characteristics suitable for precision analog circuits.

Feature Summary

• Carbon film construction providing stable resistance values
• Axial leaded design for through-hole mounting applications
• High operating temperature capability up to 155°C
• Low noise performance for sensitive signal processing

Applications

• Precision analog signal conditioning circuits
• Voltage divider networks requiring tight tolerance
• Industrial control systems operating in high-temperature environments
• Audio equipment input stages demanding low noise

Procurement Notes

Verify the specific suffix 'BD' against current manufacturer documentation to confirm packaging format and tape-and-reel specifications. Ensure compliance with latest RoHS directives by checking the most recent datasheet revision. Confirm availability of axial leads compatible with standard PCB hole sizes before finalizing procurement orders.

Selection Notes

Select this component when precise resistance values are critical in high-temperature environments. The 1/4W rating suits general-purpose discrete circuits where space allows for axial leads. Consider thermal derating curves if ambient temperatures exceed 70°C to ensure long-term reliability and prevent power rating degradation during continuous operation.

Part Context

This part belongs to Stackpole's RNF series of metal oxide and carbon film resistors. The series is designed for general-purpose electronic applications requiring reliable performance. The RNF14 variant specifically denotes the 1/4W power dissipation class within the broader family of axial leaded resistors offered by the manufacturer.

Replacement Considerations

Direct substitutes include other 17.8 Ohm, 1/4W, ±1% tolerance axial resistors from manufacturers like Vishay or Yageo. Verify physical dimensions and lead spacing match existing PCB layouts. Ensure equivalent TCR and noise specifications are maintained for critical analog applications.
