- Noise suppression in power supplies
Procurement Notes
Verify the specific suffix 'H' against official TDK/EPCOS documentation to confirm exact tolerance and material specifications. Ensure the requested quantity matches available factory packaging units. Confirm RoHS compliance status as required by project regulations. Cross-reference the full part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a current-compensated double choke is required for 250 V AC applications. The 3.3 mH inductance and 1.8 A current rating suit moderate power filtering needs. Consider the radial package size for PCB layout constraints. Verify thermal performance limits relative to the operating environment.
Part Context
This component belongs to the B82731 series of current-compensated double chokes from EPCOS. These components are designed for EMC power line filtering. The series offers various inductance values and current ratings to accommodate different circuit requirements while maintaining compact form factors.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Verify that any substitute maintains the same inductance, current rating, and voltage specifications. Ensure mechanical compatibility with existing PCB footprints.
