Procurement Notes

Verify the specific manufacturer part number against official Signal Transformer documentation to ensure compatibility with your circuit requirements. Confirm that the dual winding configuration matches your voltage and current needs. Check RoHS compliance status if required by your manufacturing standards. Ensure the through-hole package fits your PCB layout constraints.

Selection Notes

Select this component when a compact, Class 2 isolated transformer is needed for low-power applications. The dual primary allows flexibility for different input voltages. The dual secondary provides options for center-tapped or split voltage outputs. Verify thermal management requirements as the laminated core design may generate heat under full load conditions.

Part Context

The DST-4-56 belongs to the Split/Tran series from Signal Transformer. This series utilizes a dual cavity platform to provide electrical isolation and safety compliance. The product line focuses on compact power transformers suitable for space-constrained designs requiring reliable isolation between primary and secondary circuits.
