RNF18JBD47K0

Overview

The RNF18JBD47K0 is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 47 kOhms with a tight tolerance of ±0.1%. Rated for 1/8W (0.125W) power dissipation, this component utilizes a flame-retardant coating and is designed for safety applications. The unit operates within a temperature range of -55°C to +155°C and exhibits a temperature coefficient of ±100ppm/°C. Its compact axial package measures approximately 1.80mm in diameter and 3.30mm in length.

Feature Summary

• Precision metal film construction ensures stable resistive performance
• Flame-retardant coating enhances safety during operation
• Wide operating temperature range supports demanding environments

Applications

• Precision measurement circuits
• Medical instrumentation
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or bulk, as availability varies by configuration. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans. Ensure the selected variant matches the required tolerance and power rating specifications for the intended application design.

Selection Notes

Select this component when high accuracy and low drift are critical requirements. The ±0.1% tolerance distinguishes it from standard general-purpose resistors. Consider the 1/8W power rating and physical dimensions for PCB layout constraints. Verify that the ±100ppm/°C temperature coefficient meets the thermal stability needs of the circuit environment.

Part Context

This part belongs to the RNF series of precision metal film resistors from Stackpole Electronics. The series is characterized by high reliability and tight tolerances suitable for professional electronic assemblies. The axial leaded format allows for easy insertion into printed circuit boards using standard manufacturing processes.

Replacement Considerations

Check for equivalent parts with matching 47kΩ resistance, ±0.1% tolerance, and 1/8W power rating. Ensure substitute components offer similar temperature coefficients and physical dimensions for direct board replacement.
