Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version to confirm current ratings and dimensional tolerances before integration. Ensure that the ordering suffix matches the required packaging configuration. Cross-reference the part number against the manufacturer's official distribution list to avoid counterfeit components. Confirm compliance requirements such as halogen-free status if mandated by your assembly specifications.

Arrays, Signal Transformers Selection Notes

Select this component when dual isolated windings are required within a single shielded footprint. The 47 µH value suits filtering applications in moderate frequency switching regulators. Evaluate the 1.08 A and 1.14 A current limits against peak load conditions. The 7.6x7.6 mm package allows for space-constrained board layouts compared to discrete inductors.

Arrays, Signal Transformers Part Context
