Fixed Inductors Procurement Notes

Verify the specific suffix EJTS against official manufacturer documentation to confirm tolerance and packaging specifications. Confirm RoHS3 compliance status directly with the supplier or datasheet before integration. Ensure the procurement channel sources from authorized distributors to guarantee component authenticity and traceability.

Fixed Inductors Selection Notes

Select this component when a 100 nH inductance value is required in a 0402 package with a 120 mA current rating. Consider the 2.52 Ohm DC resistance impact on circuit efficiency. Evaluate the 2.1 GHz self-resonant frequency against the target operating frequency to ensure proper inductive behavior.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series utilizes ceramic drum cores and wirewound technology. Other variants in the series offer different inductance values and current ratings while maintaining the same 0402 form factor.

Fixed Inductors Replacement Considerations

Cross-reference with other 0402HM series parts such as 0402HM-910EJTS for similar electrical characteristics. Verify pin compatibility and thermal performance before substituting.
