Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct pinout and winding configuration. Confirm that the selected variant meets all necessary regulatory compliance requirements for your target market. Cross-reference the datasheet parameters with your system's thermal and electrical constraints before finalizing procurement decisions.
Selection Notes
Select this component based on its 22W power handling capability and 4.2kV isolation rating suitable for offline applications. Ensure the operating frequency range aligns with your switching controller. Verify that the through-hole package fits your PCB layout and that the thermal performance supports the required ambient temperature conditions.
Part Context
This transformer belongs to Bourns' AC to DC Flybacks product line, specifically engineered for board-mount offline applications. It serves as a critical energy storage and isolation element in switch-mode power supply designs, providing galvanic separation between primary and secondary circuits.
Replacement Considerations
Consult official Bourns documentation for confirmed substitute part numbers. Do not assume interchangeability with other series without verifying electrical and mechanical compatibility.
