Fixed Inductors Procurement Notes

Verify the specific suffix designation against official Bourns documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required thermal ratings and physical dimensions for the target assembly. Cross-reference the manufacturer's latest datasheet to validate compliance with current environmental standards and material specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component based on the requirement for a 40 µH inductance value within a through-hole axial form factor. Consider the 3 A current rating and 82 mΩ resistance limits when designing power paths. The unshielded nature requires adequate spacing in dense layouts to prevent magnetic interference with adjacent sensitive components during operation.

Fixed Inductors Part Context

This part belongs to Bourns' line of fixed inductors, specifically utilizing wirewound technology on a drum core. It serves as a passive electronic component designed for signal integrity and energy storage in various circuit topologies. The product line emphasizes reliability and consistent performance across industrial and commercial electronics applications.

Fixed Inductors Replacement Considerations

Consult the official Bourns cross-reference guide for verified substitute part numbers. Direct replacements must match the 40 µH inductance, 3 A current rating, and axial package dimensions to ensure functional compatibility without redesigning the printed circuit board footprint.
