Fixed Inductors Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance rating as documented in official datasheets. Ensure procurement sources provide traceable documentation confirming RoHS compliance and lead-free status. Cross-reference the manufacturer part number against authorized distributor lists to avoid counterfeit components. Confirm that the supplier provides valid test reports matching the specified electrical parameters.

Fixed Inductors Selection Notes

Select this component when precise low-nanohenry inductance is required for high-frequency circuit tuning. The 0402 package size suits space-constrained designs requiring surface-mount technology. Consider the 1.5 A current rating and 200 mΩ resistance for power handling requirements. Verify that the operating environment stays within the specified -55 °C to +125 °C temperature limits for reliable operation.

Fixed Inductors Part Context

This inductor belongs to the CT0402CSF series, which includes various low-inductance values ranging from 1.0 nH to higher nanohenry ratings. All parts in this series share the same 0402 physical dimensions and general construction methodology. The series is designed specifically for applications demanding minimal parasitic effects at radio frequencies.

Fixed Inductors Replacement Considerations

Compatible substitutes include other 0402 ceramic-core wire-wound inductors with 4.7 nH nominal value and ±5% tolerance. Ensure replacement parts match the 200 mΩ maximum DC resistance and 1.5 A current rating specifications.
