• Designed for axial through-hole PCB mounting

Applications

• Commercial electronic equipment
• Industrial control circuits
• General-purpose signal conditioning

Procurement Notes

Verify the specific suffix 'JB' against official Stackpole documentation to confirm packaging type, as 'B' typically denotes bulk packaging while 'JT' indicates tape and reel. Ensure the requested quantity aligns with manufacturer minimum order requirements and lead times specified in current distributor catalogs.

Selection Notes

Select this component when a 43 Ohm resistance with 5% tolerance is required for low-frequency or DC applications. Consider the 0.5W power rating and axial form factor for space-constrained through-hole designs. Verify thermal derating requirements if operating near the upper temperature limit.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The series is characterized by its flameproof construction and suitability for automated insertion processes. It serves as a standard passive component for basic circuit protection and biasing tasks.

Replacement Considerations

Compatible substitutes include other carbon film axial resistors with identical 43 Ohm, 0.5W, and ±5% specifications. Verify that alternative parts match the physical dimensions and lead configuration to ensure mechanical compatibility during assembly.
