Arrays, Signal Transformers Procurement Notes

Verify the specific suffix (e.g., LF) against the datasheet to confirm lead-free compliance and environmental classification. Ensure the ordering code matches the required inductance configuration, as series and parallel values differ significantly. Confirm humidity sensitivity level (MSL 1) and REACH status during procurement to meet regulatory requirements for your manufacturing process.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, dual-coil inductor with low DC resistance is required. The unshielded nature may necessitate careful PCB layout to minimize electromagnetic interference coupling. Consider the saturation current ratings relative to the peak load currents in both series and parallel configurations to ensure reliable operation under all expected operating conditions.

Arrays, Signal Transformers Part Context

The SMT35A-220 belongs to the SMT35A series of power inductors from Gowanda Electronics. This series is characterized by high-efficiency dual-wound toroidal designs intended for surface-mount technology. The components are often categorized under arrays or signal transformers due to their multi-coil structure, offering versatile connectivity options for circuit designers seeking customized inductive solutions.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes within the SMT35A series include models like SMT35A-102 or SMT35A-201, though these offer different inductance values. Verify that any replacement maintains the same physical footprint (13 x 9.95 mm) and electrical parameters, particularly DCR and saturation current, to ensure circuit compatibility without redesign.
