Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the 125 mA current rating aligns with the target application's thermal requirements. Cross-reference the 6.4 ohm DC resistance value with the latest datasheet revision to prevent integration errors during procurement.

Selection Notes

Select this component when high inductance accuracy is required for RF circuits. The unshielded design necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Consider the 125 mA current limit and 6.4 ohm resistance for power loss calculations in series configurations.
