Procurement Notes
Verify the specific suffix code against official TDK documentation to confirm exact electrical tolerances and packaging specifications. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the delivered components match the active status indicated in manufacturer catalogs. Cross-reference the part number with the latest datasheet revisions to avoid obsolete stock.
Selection Notes
Select this component when designing circuits requiring common-mode noise suppression for data lines. The 22 µH inductance value must align with the target frequency spectrum for interference reduction. Verify that the 0.25 A current rating exceeds the maximum operational current of the protected circuit. Ensure the 1812 package size fits the available PCB real estate constraints.
Part Context
This component belongs to the B82789C0/S0 series of SIMDAD 1812 common-mode chokes. These devices are engineered for high-performance filtering in compact electronic systems. The series is widely utilized in automotive and industrial environments where reliable signal integrity is critical. EPCOS manufactures these parts under the TDK Group umbrella.
Replacement Considerations
Consult official substitution lists for compatible alternatives within the B82789 series. Verify pin compatibility and electrical parameters before replacing.
