• Power supply output chokes for low-current applications.
• Signal processing stages in communication equipment.

Fixed Inductors Procurement Notes

Verify the specific suffix EGTS against the official datasheet to confirm the exact inductance value and tolerance, as series variations exist. Confirm RoHS3 compliance status at the time of order. Check for any Product Change Notices (PCN) or Obsolete Notices issued by Delta Electronics/Components prior to procurement to ensure long-term availability.

Fixed Inductors Selection Notes

Select this component when a precise 120 nH inductance is required in a minimal 0402 footprint. Ensure the circuit current does not exceed the 110 mA rating to prevent saturation or thermal issues. Consider the 2.66 Ohm DCR impact on voltage drop. Verify that the self-resonant frequency characteristics align with the target operating frequency.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and wirewound technology. Other variants in the series include different inductance values such as 9.1 nH, 22 nH, and 24 nH, sharing similar physical dimensions and mounting styles.

Fixed Inductors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 120 nH value, ±2% tolerance, 0402 package, and 110 mA current rating with competitor specifications.
