Fixed Inductors Procurement Notes

Verify the specific ordering suffix EJTS to ensure correct packaging and tape configuration. Confirm that the 0402 package size aligns with the designated footprint on the target PCB. Check RoHS3 compliance status if environmental regulations require it. Ensure the rated current of 400 mA meets the circuit's peak load requirements without saturation.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 24 nH is required for RF applications. Consider the 300 mΩ DCR for efficiency constraints in low-voltage circuits. The unshielded nature requires careful layout planning to minimize electromagnetic interference with nearby traces. Verify that the 1.9 GHz self-resonant frequency exceeds the operating frequency of the application.

Fixed Inductors Part Context

This part belongs to the 0402HS series of fixed inductors from Delta Electronics/Components. The series offers various inductance values in a standardized 0402 metric package. These components are designed for general-purpose high-frequency applications where space is limited. The HS designation typically indicates specific performance characteristics regarding Q-factor and current handling within the product line.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 24 nH inductors in the 0402 package with similar DCR and current ratings. Cross-reference the Q-value and self-resonant frequency to ensure equivalent RF performance. Verify that any replacement maintains the same physical dimensions for board compatibility.
