• General purpose electronic circuits
• Power supply units
• Industrial control systems

Procurement Notes

Verify the specific suffix 'JB' against official Stackpole documentation to confirm the exact tolerance and coating specifications, as distributor listings may vary. Ensure the required packaging format matches the project needs, as this series is available in bulk or tape-and-reel options depending on the specific variant ordered.

Selection Notes

Select this component when a standard 2.4 kOhm resistance is required with moderate precision. The 1/2W power rating allows for higher dissipation compared to smaller packages. Verify that the operating environment stays within the specified -55°C to +155°C range to ensure long-term reliability and adherence to the rated temperature coefficient.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The series is characterized by its robust construction and suitability for general-purpose applications. The CF12 designation indicates a 1/2W power rating within the axial leaded form factor, distinguishing it from lower-power variants like the CF06 or CF14 series.
