Fixed Inductors Procurement Notes

Verify the specific tolerance code 'J' corresponds to ±5% when ordering. Confirm RoHS compliance status as indicated by the 'F' suffix in the series designation. Ensure the axial package dimensions match the target PCB layout requirements before finalizing procurement.

Fixed Inductors Selection Notes

Select this component for low-inductance applications requiring high self-resonant frequencies. Consider the 0.65 A current rating and 0.35 Ω DC resistance for power handling needs. Compare against ferrite-core alternatives if higher inductance values are required.

Fixed Inductors Part Context

This part belongs to the CTM1F series, which offers inductance values ranging from 0.022 µH to 1,000 µH. The series provides various tolerance options including J (±5%), K (±10%), and M (±20%). The CTM1F variant specifically denotes RoHS compliance compared to the standard CTM1 series.

Fixed Inductors Replacement Considerations

Direct substitutes include other CTM1F series parts with similar inductance and tolerance, such as CTM1F-R22K or CTM1F-R22M. Cross-reference with generic axial molded inductors ensuring matching physical dimensions and electrical parameters.
