RNF14BBC3K40

Overview

The RNF14BBC3K40 is a fixed axial leaded metal film resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 3.4 kOhms 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. It exhibits a temperature coefficient of resistance (TCR) of ±25ppm/°C. The physical dimensions are 0.093 inches in diameter by 0.250 inches in length (2.35mm x 6.35mm). The device is RoHS compliant and halogen-free.

Feature Summary

• Precision metal film construction for superior electrical stability
• Flame-retardant coating standard for safety compliance
• Low temperature coefficient for consistent performance across operating ranges

Applications

• Precision measurement circuits
• High-reliability industrial equipment
• Medical instrumentation signal conditioning

Procurement Notes

Verify the specific suffix code against official datasheets to confirm tolerance and TCR ratings, as variations exist within the RNF series. Confirm packaging preferences such as bulk or tape-and-reel availability directly with authorized distributors. Ensure compliance with project-specific environmental regulations like REACH and RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when high precision and low drift are required in through-hole designs. The ±0.1% tolerance and ±25ppm/°C TCR make it suitable for critical analog applications. Compare against general-purpose variants if cost sensitivity outweighs precision requirements. Verify physical space constraints against the standard axial package dimensions.

Part Context

This resistor belongs to the RNF series of general-purpose and precision metal film resistors from Stackpole Electronics. The series offers various tolerance and TCR combinations to suit different application needs. The RNF14BBC3K40 represents the high-precision segment of this lineup, distinguished by its tight tolerance and stable thermal characteristics compared to standard commercial grade parts.

Replacement Considerations

Equivalent parts include other ±0.1% tolerance 3.4kΩ axial metal film resistors from manufacturers like Yageo or Vishay. Ensure replacement components match the ±25ppm/°C TCR and 0.25W power rating. Verify that substitute packages maintain the same axial lead spacing and body dimensions for board compatibility.
