Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct electrical parameters and packaging options. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Check for any recent lifecycle status updates or recommended replacements directly from Delta Electronics/Components documentation before finalizing procurement orders.
Selection Notes
Select this component when a 4.7 µH inductance value is required with a 300 mA current rating. Ensure the 1008 footprint fits the PCB layout constraints. Consider the 1.28 Ohm DCR impact on power loss in low-voltage applications. Verify that the unshielded nature does not interfere with nearby sensitive components due to magnetic field emission.
Part Context
This part belongs to the 1008HS series of fixed inductors from Delta Electronics/Components. The series offers various inductance values within the 1008 package size. This specific model targets applications requiring moderate inductance with compact form factors. It complements other components in Delta's passive device portfolio for RF and power management designs.
Replacement Considerations
Public sources indicate this product may no longer be produced. Consult official Delta Electronics/Components documentation for confirmed substitute part numbers. Do not assume generic equivalents are functionally identical without verifying electrical specifications and pin compatibility.
