CF12JB620K

Overview

The CF12JB620K is a carbon film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a nominal resistance of 620 kOhms with a tolerance of ±5%. The component has a power rating of 0.5W (1/2W) and operates within a temperature range of -55°C to +155°C. It utilizes an axial leaded package with dimensions of 0.142 inches in diameter and 0.374 inches in length.

Feature Summary

• Constructed using carbon film technology for stable resistive performance
• Features flameproof coating that meets UL 94V-0 safety standards
• Designed as a lower-cost alternative to wirewound components

Applications

• General purpose electronic circuits
• Consumer electronics assemblies
• Industrial control systems

Procurement Notes

Verify the specific suffix 'JB' against official Stackpole documentation to confirm it denotes the standard 5% tolerance carbon film variant rather than a specialized pulse-resistant or non-inductive type. Confirm RoHS compliance status directly with the manufacturer, as some legacy carbon film series may have different environmental declarations compared to modern metal oxide lines.

Selection Notes

Select this component when a general-purpose axial resistor is required for low-to-medium voltage applications. Ensure the circuit design accommodates the thermal characteristics of carbon film materials. Verify that the physical axial dimensions fit the PCB layout constraints and that the 0.5W power rating provides sufficient derating margin for the operating environment.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. These components are widely used in general electronics manufacturing where cost-effectiveness and standard reliability are prioritized over high-precision or high-pulse handling capabilities found in metal oxide or specialized carbon composition lines.

Replacement Considerations

CF12JT620K: Same resistance and power rating but potentially different tolerance or series designation; verify exact electrical parameters. CFM12JB620K: Metal oxide alternative offering higher stability and pulse handling; check if the application requires these enhanced properties.
