Procurement Notes

Verify the complete part number including suffix EKFS to ensure correct tolerance and packaging specifications. Confirm that the 700 mA current rating meets the application's peak and continuous load requirements. Check for RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a 390 nH inductance value is required in a compact 1008 footprint. Ensure the operating environment supports the specified temperature range. Consider the unshielded nature of the device regarding potential electromagnetic interference coupling with nearby sensitive traces or components during layout.

Part Context

This component belongs to the 1008HS series of ferrite-based wirewound inductors. The series offers various inductance values within the 1008 package size, catering to high-frequency applications where space constraints are critical. The HS designation typically indicates specific material properties optimized for these frequencies.

Replacement Considerations

Direct substitutes must match the 390 nH inductance, 1008 package dimensions, and similar current handling capabilities. Verify that any alternative component maintains comparable self-resonant frequency and DC resistance to ensure circuit performance parity.
