Procurement Notes

Verify the specific suffix JB indicates the correct tolerance and series variant against official Stackpole documentation. Confirm that the axial lead form factor matches your board layout requirements. Ensure compliance with local environmental regulations regarding RoHS3 status before finalizing procurement specifications.

Selection Notes

Select this component when a 7.5 MOhm resistance is required in a 1/2W axial package. Consider the -1500ppm/°C temperature coefficient for thermal stability analysis. Verify that the physical size fits within the designated footprint on the printed circuit board design.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The series is characterized by its reliability in general-purpose applications. The CF designation typically denotes standard carbon film construction, while the numeric codes specify power rating and case size.

Replacement Considerations

Direct substitutes must match the 7.5 MOhm resistance, 1/2W power rating, and axial package. Verify equivalent temperature coefficients and voltage ratings. Cross-reference with other manufacturers' carbon film axial resistor lines offering similar dimensional constraints.
