- Interference suppression in electronic equipment
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm exact mechanical dimensions and tolerance grades. Ensure compatibility with existing PCB layouts regarding lead spacing and height constraints. Cross-reference datasheet revisions to confirm material compliance and RoHS status prior to integration into final designs.
Selection Notes
Select this component when dual-channel common-mode filtering is required at 27 mH. Verify that the 900 mA current rating meets circuit load requirements. Confirm that the 750 Ohm DC resistance does not introduce excessive voltage drop. Ensure the 250 V AC rating aligns with the system's operating voltage levels.
Part Context
This part belongs to the B82732 series of power line chokes from EPCOS. These components are engineered for electromagnetic compatibility (EMC) in industrial settings. The series typically offers various inductance values and current ratings to suit different power line filtering needs across diverse electronic systems.
Replacement Considerations
Consult official TDK substitution guides for verified equivalents. Generic cross-references may differ in core material or saturation characteristics. Validate mechanical fit and electrical performance before replacing.
