CF14JB4K30

Overview

The CF14JB4K30 is a fixed axial leaded carbon film resistor manufactured by Stackpole Electronics Inc. It features a nominal resistance of 4.3 kOhms with a tolerance of ±5%. The component has a power rating of 0.25W (1/4W) and operates within a temperature range of -55°C to +155°C. Its physical dimensions are 2.30mm in diameter by 6.00mm in length. The device complies with RoHS3 standards and carries an ECCN classification of EAR99.

Feature Summary

• Utilizes carbon film technology for stable resistive performance
• Designed for through-hole mounting on printed circuit boards
• Complies with RoHS3 environmental regulations

Applications

• General-purpose electronic circuits requiring standard resistance values
• Consumer electronics assemblies
• Industrial control systems

Procurement Notes

Verify the specific suffix 'JB' against official datasheets to confirm the 5% tolerance and 1/4W rating, as variations exist within the CF series. Confirm that the required package matches the axial leaded configuration. Ensure compliance with project-specific environmental standards such as RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when a 4.3 kOhm resistance value with ±5% tolerance is required for through-hole applications. Consider the 0.25W power rating and the wide operating temperature range of -55°C to 155°C. Ensure the axial package dimensions fit the available PCB space and that the carbon film composition meets the circuit's noise and stability requirements.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The CF series offers various resistance values and tolerances for general electronic use. The CF14JB4K30 specifically denotes the 4.3 kOhm variant within this family, sharing common manufacturing processes and material properties with other parts in the series.

Replacement Considerations

The CF14GB4K30 is listed as a parameter-equivalent alternative. Verify that the substitute maintains the same 4.3 kOhm resistance, ±5% tolerance, and 1/4W power rating. Confirm compatibility regarding package type and environmental certifications before substitution.
