Power Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required electrical parameters and mechanical dimensions. Confirm that the package type matches bulk handling requirements and that the pin configuration aligns with the target printed circuit board layout before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when an open-style laminated transformer with split bobbin architecture is required for horizontal mounting. Ensure the application demands a 2.4VA rating and compatible input/output voltage levels. Validate that the through-hole form factor fits the assembly constraints and that the operating frequency range aligns with standard low-frequency power conversion needs.

Power Transformers Part Context

This part belongs to the ST3 series of laminated transformers manufactured by Pulse Electronics. The series offers various configurations in terms of voltage ratings and current capacities while maintaining a consistent open-style, split bobbin design suitable for horizontal plug-in applications across different power levels within the family.

Power Transformers Replacement Considerations

Cross-reference with DST3-56B33 or other ST3 series variants with matching 2.4VA ratings and identical pinout specifications. Verify that substitute parts maintain the same laminated core construction and horizontal plug-in mechanical footprint to ensure direct interchangeability without redesigning the host circuit board.
