Procurement Notes

Verify the specific datasheet version to confirm electrical parameters such as winding resistance and isolation voltage, as these values are critical for circuit design. Ensure the ordering suffix matches the required packaging configuration. Cross-reference with official manufacturer documentation to validate compatibility with intended thermal and electrical operating conditions before finalizing procurement.

Selection Notes

Select this component when a 152 µH inductance value is required in a surface-mount package. Consider the physical dimensions and pin configuration against available PCB footprint constraints. Evaluate the thermal performance and isolation requirements relative to the specific application environment to ensure reliable operation within specified limits.

Part Context

This part belongs to the Pulse Electronics family of surface-mount power transformers. It is categorized under flyback transformers, distinguishing it from standard chokes or inductors by its multi-winding structure designed for energy transfer and isolation rather than simple energy storage.

Replacement Considerations
