Power Transformers Procurement Notes

Verify the specific secondary voltage rating matches the target application design, as the PE4121-I series includes multiple variants with different output configurations. Confirm that the 8VA power rating and 3.75KV isolation level meet the safety requirements of the end product. Ensure the PCB footprint aligns with the pin spacing specifications provided in the official datasheet before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when a compact 8VA isolation transformer is required for 230V input systems. The 18V secondary output suits low-power downstream rectification circuits. Consider the operating temperature range and physical dimensions to ensure compatibility with the enclosure constraints. Verify that the parallel primary configuration matches the available mains supply infrastructure.

Power Transformers Part Context

This model belongs to the PE4121-I series of PCB safety isolation transformers manufactured by PowerUC Electronics. The series is characterized by its use of laminated cores and standardized pin-out designs suitable for automated assembly processes. These components are engineered to provide reliable galvanic isolation between primary mains voltages and secondary low-voltage circuits in various electronic assemblies.

Power Transformers Replacement Considerations

Direct substitutes must match the 8VA rating, 230V primary, 18V secondary specification, and EI core form factor. Verify that alternative components maintain equivalent 3.75KV isolation ratings and compatible PCB pin spacing to ensure mechanical and electrical interchangeability without redesigning the host circuit board.
