RNF14JBD820R

Overview

The RNF14JBD820R is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a nominal resistance of 820 Ohms with a tight tolerance of ±1%. The component is rated for 0.25W (1/4W) power dissipation and operates within a temperature range of -55°C to +155°C. It exhibits a temperature coefficient of ±100ppm/°C and includes a flame-retardant safety coating.

Feature Summary

• Precision metal film construction ensures stable electrical performance
• Flame-retardant safety coating enhances operational safety
• Axial leaded package facilitates standard through-hole mounting

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the required ±1% tolerance and flame-retardant coating, as generic series designations may vary. Confirm RoHS3 compliance status directly from the manufacturer datasheet prior to integration. Ensure the axial package dimensions match the target PCB footprint constraints.

Selection Notes

Select this component when circuit stability requires tighter tolerances than standard carbon film resistors provide. The metal film composition offers superior noise characteristics compared to thick film alternatives. Verify that the 0.25W power rating suffices for the intended thermal environment without derating.

Part Context

This part belongs to the RNF series of general-purpose and precision metal film resistors. It shares the axial form factor with other Stackpole axial components but distinguishes itself through the combination of 1% tolerance and safety coatings. It serves as a higher-precision alternative to the CF series carbon film resistors.

Replacement Considerations

The RNF14JBD820R is functionally equivalent to the RNF14FTD820R regarding resistance and tolerance, though packaging or coating specifications may differ. Cross-reference with Vishay Dale RN55E8200FB14 for similar precision requirements.
