• Vertical cylinder radial package for standard PCB mounting
• RoHS compliant and lead-free manufacturing

Fixed Inductors Applications

• General purpose signal filtering circuits
• Power supply input/output stages
• Electronic equipment electromagnetic interference suppression

Fixed Inductors Procurement Notes

Verify the specific suffix '331K' to confirm the 330 µH inductance value and 1.1 A current rating. Ensure the procurement documentation explicitly states RoHS compliance and lead-free status. Confirm the radial vertical package dimensions match the target PCB footprint requirements before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a 330 µH inductance value is required with a 1.1 A current handling capability. The unshielded design is appropriate for applications where magnetic coupling with adjacent components is not a primary concern. Consider the 650 mΩ DCR limit for efficiency calculations in low-voltage power paths.

Fixed Inductors Part Context

This part belongs to the CTRFB series of fixed inductors from Central Technologies. The series offers various inductance values within radial packages. The CTRFB0810F-331K specifically denotes the 330 µH variant within this family, sharing common mechanical and environmental characteristics with other models in the same product line.

Fixed Inductors Replacement Considerations

Cross-reference with CTRFB0810F-332K for higher inductance needs or CTRFB0810F-101K for lower inductance options within the same physical package. Verify that substitute parts maintain identical current ratings and DCR specifications to ensure circuit performance consistency.
