Fixed Inductors Procurement Notes

Verify the ordering suffix carefully; 'K' denotes ±2% tolerance while 'J' indicates ±5%. Confirm RoHS3 compliance status during procurement. Check moisture sensitivity level (MSL 1) handling requirements. Ensure the specific reel quantity matches production needs. Validate the manufacturer part number against official Delta documentation before finalizing orders.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance near 1.2 nH is required for high-frequency signal paths. The unshielded design minimizes parasitic effects but requires careful layout to avoid coupling. Consider the 740 mA current rating for power handling limits. The ceramic drum core offers stability across the specified temperature range. Evaluate the 90 mΩ DCR impact on circuit efficiency.

Fixed Inductors Part Context

This part belongs to the 0402HS series of high-frequency inductors from Delta Electronics. The series utilizes wirewound technology on ceramic cores to achieve precise low-nanohenry values. These components are engineered for RF and microwave applications where standard inductors fail due to self-resonance limitations. The 0402 package allows for miniaturization in modern electronic devices.

Fixed Inductors Replacement Considerations

The 0402HS-1N2EJTS is a direct substitute with identical electrical parameters but a different tolerance specification (±5% vs ±2%). Verify that the tolerance difference meets the circuit design requirements. Other parts in the 0402HS series may offer different inductance values or tolerance grades.
