Procurement Notes
Verify the complete part number including suffixes against official TDK-EPCOS documentation to ensure correct specifications. Confirm that the required inductance, current rating, and mounting style match the specific circuit requirements. Check for any recent product lifecycle changes or obsolescence notices directly from the manufacturer before placing orders.
Selection Notes
Select this component when high common mode rejection is required for power lines carrying up to 6.0 A. Ensure the PCB layout accommodates the through-hole package dimensions and height constraints. Verify that the operating temperature range aligns with the system's thermal environment and that the insulation voltage meets safety standards.
Part Context
This component belongs to the B82725S series of current-compensated ring core double chokes from TDK-EPCOS. These components are engineered for robust electromagnetic interference suppression in power supply inputs. The series offers various inductance values and current ratings to suit different power line filtering needs across industrial and consumer electronics.
Replacement Considerations
Consult official TDK-EPCOS substitution guides for verified alternative part numbers. Ensure any replacement maintains identical inductance, current rating, and physical footprint. Cross-reference datasheets to confirm equivalent thermal and electrical performance characteristics.
