Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as availability varies by distributor. Confirm RoHS3 compliance status during final procurement review to ensure adherence to environmental regulations. Cross-reference manufacturer part numbers against distributor databases to prevent substitution errors due to similar naming conventions across different series.

Fixed Inductors Selection Notes

Select this component when circuit design requires a 33 nH inductance value within a strict 0402 spatial constraint. Evaluate the 400 mA current rating against peak load requirements to prevent saturation. Consider the 350 mΩ DC resistance impact on power loss efficiency. Ensure the 2.35 GHz self-resonant frequency aligns with the target operating bandwidth to maintain impedance characteristics.

Fixed Inductors Part Context

This part belongs to the 0402HS series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and wirewound technology to deliver consistent electrical parameters across various inductance values. The 0402HS designation indicates the specific case size and series family, distinguishing it from shielded or alternative core material variants within the manufacturer's portfolio.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402HS series parts with identical electrical specifications. Verify physical dimensions and terminal configurations before integration. Alternative manufacturers may offer compatible components but require validation of Q-factor and self-resonant frequency curves.
