Procurement Notes

Verify the specific datasheet version for the PA1528NL to confirm exact electrical tolerances and pinout configurations before integration. Ensure that the surface mount footprint matches the PCB layout requirements of 14.00mm by 13.11mm. Confirm thermal management strategies align with the maximum operating temperature of 130°C and the specified power rating limits under actual load conditions.

Selection Notes

Select this component when a compact, high-frequency pulse transformer is required for isolated power stages. The 28.9µH inductance and 200 kHz frequency rating make it suitable for modern switching regulators. Consider the physical height constraint of 12.32mm for low-profile enclosure designs. Verify compatibility with the target circuit's voltage isolation requirements and current handling capabilities against the manufacturer's specifications.

Part Context

This part belongs to the EP13 platform series from Pulse Electronics, which focuses on high-frequency wire-wound transformers for surface mount applications. The series is engineered to support power ranges up to 60W while maintaining small form factors. These components are typically used in industrial and consumer electronics where space efficiency and high-frequency performance are critical design parameters.

Replacement Considerations

The PA1528ANL is a related variant within the same product family. Verify if the ANL suffix denotes any functional differences or packaging changes before substitution. Cross-reference electrical parameters such as inductance and frequency response to ensure compatibility with the existing circuit design.
