Power Transformers Feature Summary

• Vacuum epoxy resin encapsulation ensures high dielectric strength and long working life.
• Laminated core construction supports efficient power transformation for PCB applications.
• Dual secondary windings provide isolated outputs suitable for balanced circuits.

Power Transformers Applications

• General purpose AC to DC power supply units
• Industrial control system power modules
• Consumer electronics requiring isolated low-voltage DC

Power Transformers Procurement Notes

Verify the specific secondary configuration matches the design requirement, as the PE3518-I series includes variants with different voltage outputs such as 6V or 24V. Confirm that the 230V primary rating aligns with the local mains frequency and voltage standards. Ensure the PCB footprint accommodates the pin spacing specified in the official datasheet before finalizing procurement.

Power Transformers Selection Notes

Select this component when a 5VA capacity is sufficient for the load requirements. The dual 15V secondary allows for split-rail power supplies or full-wave rectification configurations. Consider the operating temperature range if the device will be enclosed in a space with limited airflow. Verify that the physical dimensions fit the available board real estate compared to other EI-series transformers.

Power Transformers Part Context

This transformer belongs to the PE series of safety isolation transformers manufactured by Beijing Yaohuadechang Electronic Co (YHDC). These components are widely distributed by electronics suppliers such as PowerUC Electronics and Radwell. The series is characterized by vacuum epoxy encapsulation and high-temperature aging processes to ensure reliability in various electronic assemblies.

Power Transformers Replacement Considerations

Direct substitutes include other PE3518-I variants with identical 5VA ratings and 230V primary inputs but different secondary voltages, such as PE3518-I-2301501. Cross-referencing pinouts and mechanical dimensions is essential when replacing with generic EI35 transformers from other manufacturers.
