Fixed Inductors Procurement Notes

Verify the specific suffix EJTS against official datasheets to confirm tolerance and packaging details. Ensure compatibility with standard reflow soldering profiles for 0402 components. Check RoHS3 compliance status as required by target market regulations before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0402 package size and low inductance values near 39 nH are necessary. Consider the 200 mA current rating and 550 mΩ DCR for power loss calculations. Compare self-resonant frequency specifications against circuit operating frequencies to ensure effective performance.

Fixed Inductors Part Context

This part belongs to the 0402HS series of wirewound inductors from Delta Electronics/Components. The series focuses on compact form factors for dense PCB layouts. Similar parts in the series vary primarily in inductance value, current rating, and DC resistance while maintaining the same physical dimensions and core technology.

Fixed Inductors Replacement Considerations

Cross-reference with other 0402 wirewound inductors offering 39 nH ±5% tolerance. Verify that substitute components match the 200 mA current rating and 550 mΩ DCR limits. Ensure the replacement maintains the same package dimensions and mounting type for mechanical compatibility.
