Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates potential non-compliance depending on specific manufacturing batch or revision. Confirm axial lead dimensions match target PCB footprint requirements. Ensure operating temperature range meets system environmental constraints. Validate that the 149 mA current rating satisfies circuit load demands without saturation.

Fixed Inductors Selection Notes

Select this component when a 27 µH inductance value is required with tight ±5% tolerance. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. The axial form factor suits manual assembly or wave soldering processes where standard through-hole technology is preferred over surface mount alternatives.
