Fixed Inductors Procurement Notes

Verify the specific suffix EJTS against official Delta Electronics documentation to confirm packaging type and tolerance specifications. Ensure that the ordering information matches the required 0402 footprint dimensions and thermal characteristics for your PCB layout. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and availability status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 9 nH is required for high-frequency operation. The unshielded design necessitates careful placement to avoid magnetic coupling with nearby components. Verify that the 1.4 A current rating exceeds the maximum expected load current to prevent saturation. Consider the 0402 package size constraints regarding soldering reflow profiles and mechanical stress limits during assembly.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors, characterized by high-performance specifications in a compact form factor. The series utilizes ceramic cores and wirewound technology to achieve high self-resonant frequencies suitable for RF and microwave applications. It complements other variants in the lineup offering different inductance values while maintaining consistent physical dimensions and mounting standards.

Fixed Inductors Replacement Considerations

Direct substitutes include 0402HP-9N5EGTS and 0402HP-1N0EJTS from the same manufacturer series. Verify that alternative parts match the 9 nH inductance, 1.4 A current rating, and 80 mΩ DCR specifications. Ensure the replacement maintains the unshielded drum core construction and 0402 package dimensions to fit existing footprints without redesign.
