Procurement Notes
Verify the specific ordering suffix against official TDK documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration. Check for any recent product change notices or end-of-life announcements that may affect long-term availability and supply chain stability.
Selection Notes
Select this component when a 27 mH inductance value is required for common mode noise reduction. Ensure the circuit design accommodates the specified 900 mA current rating without saturation. Verify that the PCB footprint matches the 12.5 mm lead spacing and that the operating environment stays within the -40°C to +125°C thermal limits defined for this series.
Part Context
This part belongs to the B82732W series of current-compensated D-core double chokes. These components are engineered for robust performance in power line filtering applications. The series utilizes ferrite cores to provide high inductance values while maintaining compact physical profiles suitable for various industrial and consumer electronic assemblies.
Replacement Considerations
Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may not match the precise inductance tolerance or thermal characteristics required for critical EMC performance.
