It features an unshielded drum core construction with a nominal inductance of 3.9 µH. The component utilizes vertical cylinder packaging with leads that are easily formable to the specified 'F' dimension. It is compliant with RoHS standards and lead-free requirements.

Fixed Inductors Feature Summary

• Radial leaded construction with formable leads for assembly flexibility
• Unshielded drum core design suitable for peaking applications
• RoHS compliant and lead-free manufacturing

Fixed Inductors Applications

• Peaking coil circuits
• General purpose filtering
• Signal conditioning

Fixed Inductors Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm tolerance and current ratings. Ensure the ordering part number matches the required inductance value of 3.9 µH. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the lead formability dimensions with the mechanical drawing provided in the product documentation.

Fixed Inductors Selection Notes

Select this component when a low-inductance peaking coil is required for circuit tuning. Consider the radial package style for through-hole mounting processes. Evaluate the unshielded nature of the drum core regarding potential magnetic interference with nearby components. Verify that the physical dimensions fit within the available board space constraints.

Fixed Inductors Part Context

This part belongs to the CTRL5480F series of fixed inductors from Central Technologies. The series offers various inductance values ranging from 3.9 µH to 22,000 µH. Other variants include different suffixes indicating specific inductance tolerances or values, such as the 100K or 223K models, all sharing similar radial construction characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes may include other parts from the Central Technologies CTRL5480F family with matching inductance. Generic radial fixed inductors with equivalent electrical parameters can be considered if mechanical fit and lead formability are verified.
