Arrays, Signal Transformers Procurement Notes

Verify the complete ordering code includes the suffix '900' to confirm the dual-coil array variant. Standard single-coil versions lack this suffix. Confirm AEC-Q200 compliance requirements match your specific automotive application protocols. Ensure the selected package matches your automated surface-mount assembly equipment specifications.

Arrays, Signal Transformers Selection Notes

Select this component when dual independent inductors are required in a single footprint. Compare parallel versus series configurations based on current handling needs. Verify saturation current ratings against peak load conditions. Ensure the 12.50mm x 12.50mm package dimensions fit the available PCB real estate constraints.

Arrays, Signal Transformers Part Context

This part belongs to the B82477D4 series of SMD power inductors manufactured by EPCOS, now TDK Electronics. The series is characterized by high current capability and low DC resistance. These components are widely used in automotive electronics due to their robust construction and standardized mounting profiles.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other B82477D4 series variants with matching inductance values. Verify pin compatibility and physical dimensions before substitution. Alternative manufacturers may offer similar shielded dual-coil arrays but require re-validation of thermal and electrical performance.
