Fixed Inductors Procurement Notes

Verify the specific suffix 'K' indicates the required tolerance level against official datasheets. Confirm package dimensions match the 0402 (1005 metric) footprint requirements. Ensure the supplier provides valid RoHS compliance documentation. Check for moisture sensitivity level constraints during storage and handling procedures.

Fixed Inductors Selection Notes

Select this component when low inductance values are critical for RF tuning. Compare the 66 mΩ DCR against circuit loss requirements. Evaluate the 840 mA current rating against peak load conditions. Consider the 5.8 GHz self-resonant frequency limit for operational bandwidth.

Fixed Inductors Part Context

This part belongs to the 0402HS series of ceramic RF inductors. It shares the same physical 0402 footprint as other variants but differs in electrical characteristics such as inductance and current ratings. The series is designed for compact high-frequency applications requiring stable performance.

Fixed Inductors Replacement Considerations

Direct substitutes include 0402HS-3N9EGTS and 0402HS-3N9EJTS from the same manufacturer. These alternatives offer similar form factors but may differ in tolerance or current specifications. Verify electrical parameters before substitution.
