Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel or cut tape, as these affect handling procedures. Confirm that the RoHS3 compliance status meets environmental regulations for your target market. Cross-reference the manufacturer part number with distributor codes to avoid procurement errors during sourcing.

Fixed Inductors Selection Notes

Select this component when a compact 72 nH inductance is required for high-frequency applications up to 2.5 GHz. Ensure the 135 mA current rating aligns with circuit requirements to prevent saturation. Consider the 2.1 Ohm DC resistance impact on power loss. Verify that the 0402 footprint matches the PCB layout constraints.

Fixed Inductors Part Context

This inductor belongs to the 0402HM series, which focuses on high-performance wirewound designs using ceramic cores. The series is engineered for miniaturized electronics requiring precise inductance values in small form factors. It complements other Delta components like the 0805CS series by offering smaller dimensions for dense board layouts.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 0402 wirewound inductors with 72 nH inductance and similar current ratings. Verify compatibility regarding self-resonant frequency and Q factor. Check if alternative manufacturers offer equivalent ceramic core constructions. Ensure the replacement maintains the same thermal characteristics and mounting dimensions.
