Procurement Notes

Verify the specific manufacturer part number against official Delta Electronics documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with standard SMT reflow profiles and check RoHS compliance status prior to integration into production lines.

Selection Notes

Select this component when precise 820 nH inductance is required in a compact 1008 footprint. Consider the 400 mA current rating and 1.61 Ohm DCR for power loss calculations. The unshielded nature requires layout consideration to minimize electromagnetic interference with nearby traces.

Part Context

This part belongs to the 1008CS series of fixed inductors manufactured by Delta Electronics/Components. The series provides various inductance values within the 1008 package size, catering to applications requiring small form factors and reliable performance in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 1008CS series variants such as 1008CS-120EKTS or 1008CS-181EKTS if different inductance values are acceptable. Verify pinout and thermal characteristics before swapping with generic equivalents.
