Procurement Notes

Verify the specific packaging configuration, as sources indicate both bulk and tape-and-reel options exist for this part number. Confirm the manufacturer's standard lead time of 19 weeks aligns with project schedules. Ensure the selected variant matches the required environmental certifications, specifically RoHS3 compliance, before finalizing procurement orders.

Selection Notes

Select this component when a high-resistance value of 8.2 Mohm is required in a compact axial form factor. The 0.5W power rating suits low-current applications. Consider the operating temperature range of -55°C to +155°C for environments with thermal variations. Verify that the ±5% tolerance meets the circuit's precision requirements compared to tighter tolerance alternatives.

Part Context

This resistor belongs to the CF series of carbon film components from Stackpole Electronics. The 'JB' suffix typically denotes specific construction characteristics within this line. It serves as a fundamental passive component for general electronics, offering a balance of electrical stability and physical durability for standard industrial and consumer applications.

Replacement Considerations

Direct substitutes must match the 8.2 Mohm resistance, 0.5W power rating, and axial package. Verify compatibility of temperature coefficients and tolerance levels. Cross-reference with other manufacturers' carbon film axial resistors having identical dimensional constraints and electrical specifications.
