RNF14FTE576K

Overview

The RNF14FTE576K is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 576 kOhms with a tolerance of ±1%. The component has a power rating of 0.25W (1/4W) and a temperature coefficient of ±25 ppm/°C. Rated for a maximum working voltage of 250V, it operates within a temperature range of -55°C to +155°C. The physical dimensions are 2.35 mm in diameter and 6.35 mm in length.

Feature Summary

• Precision metal film construction ensures superior electrical stability and low temperature coefficient performance.
• Standard flame-retardant coating provides enhanced safety characteristics for general-purpose applications.
• RoHS compliant and lead-free available, meeting environmental regulatory standards.

Applications

• General purpose electronic circuits
• Precision signal conditioning networks
• Industrial control equipment

Procurement Notes

Verify the specific suffix 'E' indicates reel packaging when ordering. Confirm RoHS3 compliance status for current production lots. Ensure the ±25 ppm/°C temperature coefficient meets circuit thermal requirements. Validate that the 250V working voltage rating is sufficient for the target application environment.

Selection Notes

Select this component for applications requiring high precision and stability over a wide temperature range. The ±25 ppm/°C TCR offers better thermal performance than standard 100 ppm variants. The axial form factor facilitates manual insertion or wave soldering processes where surface mount options are unsuitable.

Part Context

This part belongs to the RNF/RNMF series of general-purpose metal film resistors from Stackpole Electronics. The series is designed to replace older carbon composition types with more stable thin-film alternatives. The RNMF variant represents the miniaturized version of this same technology family.

Replacement Considerations

RNMF14FTC576K is a miniaturized axial alternative within the same series offering similar electrical specifications in a smaller package.
