Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by Delta Electronics/Components. Procurement should focus on identifying verified direct substitutes or alternative sources that guarantee authenticity. Buyers must verify the condition of any available stock, as original inventory may be limited or discontinued. Ensure that replacement parts meet the same electrical specifications and form factor requirements to maintain system integrity.

Selection Notes

When selecting this component, prioritize its 2.2 µH inductance and 500 mA current rating against circuit requirements. Note the 950 mOhm DCR impact on efficiency. The 1008 package size dictates board space constraints. Verify compatibility with peak operating temperatures up to 125°C. Consider the lack of shielding if EMI sensitivity is a concern. Confirm that the self-resonant frequency aligns with the target signal bandwidth.

Part Context

The 1008HS-222EJFS belongs to the 1008HS series of fixed inductors, which are characterized by their use of ceramic cores and wound wire designs. This series is part of Delta Electronics' portfolio of passive magnetic components intended for various market segments including automotive and cloud computing equipment. The 1008 footprint offers a balance between inductance value and physical size for surface mount applications.

Replacement Considerations

The 744758322A is listed as a direct substitute for the 1008HS-222EJFS. Verify that the substitute matches the 2.2 µH inductance, 500 mA current rating, and 1008 package dimensions. Ensure the substitute's DC resistance and self-resonant frequency are compatible with the original design specifications.
