CF12JB1R50

Overview

The CF12JB1R50 is a carbon film through-hole resistor manufactured by Stackpole Electronics Inc. It features an axial leaded package with a resistance value of 1.5 ohms and 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. Its physical dimensions are 2.70mm in diameter by 8.50mm in length. The device complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Flame retardant coating for enhanced safety
• Carbon film technology for stable performance
• Axial leaded format for PCB mounting

Applications

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

Procurement Notes

Verify the manufacturer part number CF12JB1R50 against official Stackpole documentation to ensure authenticity. Confirm that the axial package style and 1.5-ohm resistance match your circuit design requirements. Check for RoHS3 compliance status if environmental regulations apply to your manufacturing process. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when a low-resistance, high-tolerance axial resistor is required for general applications. The 1.5-ohm value suits current sensing or termination tasks. Consider the 0.5W power rating for moderate load conditions. The flame-retardant coating adds a layer of safety compared to standard carbon film resistors without specialized coatings.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The 'J' suffix indicates a ±5% tolerance, while 'B' denotes the specific resistance value code. It is distinct from metal oxide or wirewound variants in the same product family, offering a balance of cost-effectiveness and reliability for standard electronic assemblies.

Replacement Considerations

Direct substitutes include other manufacturers' 1.5-ohm, 1/2W, ±5% axial carbon film resistors. Verify that replacement parts share the same physical dimensions and terminal configuration for board compatibility. Ensure equivalent power derating curves and temperature coefficients are acceptable for the specific application environment.
