Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version when sourcing, as documentation may list varying inductance values such as 34.8 µH or 50.5 µH. Confirm the manufacturer is Pulse Electronics Corporation. Ensure the part number suffix matches the required configuration. Cross-reference electrical parameters like DCR and saturation current against your circuit requirements before finalizing procurement decisions.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-coil SMT inductor is required for space-constrained designs. Evaluate the 73 mΩ DCR and 6 A saturation current against load requirements. Compare the 50.5 µH inductance value with alternative models like PE-54041NL if leaded mounting is acceptable. Ensure thermal performance aligns with the operating environment.

Arrays, Signal Transformers Part Context

The P0403NL belongs to the Pulse Electronics Power Inductor family, specifically categorized as a coupled inductor array. It serves as an alternative to discrete inductor setups, offering integrated magnetic coupling. The component is distinct from the PA5403 series due to its coupled coil structure and SMT form factor.
