Procurement Notes
Verify component authenticity against manufacturer specifications before integration. Confirm RoHS status as non-compliant per available data. Ensure supply chain sources provide valid traceability documentation. Cross-reference part numbers to avoid confusion with similar series variants. Validate physical dimensions for PCB layout compatibility prior to procurement.
Selection Notes
Select this component for applications requiring high inductance in a small radial form factor. Consider the low maximum DC current rating when designing power paths. Evaluate the self-resonant frequency to ensure operation within the desired bandwidth. Compare DC resistance against circuit loss requirements. Assess mechanical stability for axial mounting configurations.
