RNF14FBD33R2

Overview

The RNF14FBD33R2 is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a nominal resistance of 33.2 ohms with a tolerance of ±0.1%. The component has a power rating of 0.25W (1/4W) and operates within a temperature range of -55°C to +155°C. Its temperature coefficient of resistance is ±25ppm/°C. The physical dimensions are 2.35mm in diameter and 6.35mm in length, conforming to standard axial packaging.

Feature Summary

• Precision metal film construction for superior electrical stability
• Flame-retardant coating for enhanced safety compliance
• Low temperature coefficient ensuring consistent performance across wide thermal ranges

Applications

• Precision measurement circuits requiring stable low-resistance values
• High-reliability industrial control systems
• Medical instrumentation signal conditioning
• Automotive electronics testing equipment

Procurement Notes

Verify the specific suffix 'BD' indicates the required 0.1% tolerance and ±25ppm/°C TCR against official datasheets before ordering. Confirm RoHS3 compliance status for your region. Check lead times as standard delivery may vary. Ensure axial lead spacing matches your PCB footprint requirements.

Selection Notes

Select this part when high precision and low drift are critical. The 0.1% tolerance offers tighter accuracy than standard 1% resistors. Consider the ±25ppm/°C TCR for environments with significant temperature fluctuations. Verify that the 0.25W power rating suits the circuit's dissipation needs.

Part Context

This component belongs to the RNF series of general-purpose metal film resistors from Stackpole Electronics. The series is designed for applications demanding better stability and lower noise than carbon composition types. It serves as a reliable alternative for legacy designs requiring precise analog signal handling.

Replacement Considerations
