Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the official Bourns datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the procurement channel provides valid traceability documentation. Confirm that the received components match the physical dimensions and marking codes listed in the manufacturer's official product documentation before integration into production lines.

Fixed Inductors Selection Notes

Select this component when a high inductance value is required within a compact surface-mount footprint. The unshielded design necessitates careful layout planning to manage electromagnetic interference with adjacent sensitive traces. Evaluate the 140 mA current limit against peak load requirements to prevent saturation during operation.
