Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tolerance and parameter accuracy. Ensure compatibility with axial through-hole assembly processes. Confirm RoHS compliance status via the latest datasheet as regulatory requirements may vary by production batch.

Selection Notes

Select this component when a 10 µH inductance with 2% tolerance is required for RF circuits. Consider the 95 mA current rating and 5.2 Ohm DC resistance for power handling limits. The unshielded design requires adequate spacing to prevent magnetic coupling interference with adjacent components.
