RNF14DBC36K5

Overview

The RNF14DBC36K5 is a precision metal film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 36.5 kOhms with a tight tolerance of ±0.5%. 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 low temperature coefficient of ±50 ppm/°C and has a voltage rating of 250V. Physical dimensions are 2.35mm in diameter and 6.35mm in length, housed in an axial package suitable for PCB mounting.

Feature Summary

• Precision metal film construction ensures stable electrical performance
• Flame-retardant coating provides enhanced safety compliance
• Low temperature coefficient maintains accuracy across wide thermal ranges
• Axial leaded design facilitates standard through-hole PCB integration

Applications

• General purpose electronic circuits requiring precise resistance values
• Industrial control systems demanding high stability
• Test and measurement equipment calibration networks
• Medical device signal conditioning stages

Procurement Notes

Verify the specific suffix DBC indicates the 0.5% tolerance and 50 ppm/°C coefficient variant within the RNF series. Confirm RoHS3 compliance status for current manufacturing lots. Ensure packaging type matches project requirements, as bulk or tape options may vary by distributor. Cross-reference the full part number against official Stackpole datasheets to validate voltage ratings and physical dimensions before finalizing procurement specifications.

Selection Notes

Select this component when circuit design requires tighter tolerance than standard 1% resistors but does not necessitate ultra-high precision classes. The 0.25W power rating suits low-power signal processing applications. Consider the axial form factor for manual assembly or automated insertion processes where surface mount alternatives are unsuitable. Verify operating temperature constraints align with the -55°C to +155°C specification.

Part Context

This resistor belongs to the RNF/RNMF series of precision metal film components from Stackpole Electronics. The series is characterized by flame-retardant coatings and low noise characteristics. The RNF14DBC36K5 represents a specific value within this family, distinguished by its 0.5% tolerance and 50 ppm/°C temperature coefficient, positioning it between standard general-purpose and ultra-precision resistor categories.

Replacement Considerations

Compatible substitutes include other manufacturers' 36.5k Ohm, 0.5% tolerance, 1/4W axial metal film resistors with equivalent temperature coefficients. Verify physical footprint compatibility, specifically the 2.35mm diameter and 6.35mm length. Ensure replacement parts meet the same RoHS3 and flame-retardant coating standards required by the original design.
