Procurement Notes

Verify the specific datasheet version to confirm exact pinout assignments and thermal characteristics before integration. Ensure that the selected mounting orientation accommodates the specified physical dimensions of 47.6 mm by 36.5 mm. Confirm that the operating environment remains within the standard temperature limits defined by the manufacturer for laminated core transformers.

Selection Notes

Select this component when a 10 VA isolation transformer is required for dual-voltage primary inputs. The dual secondary outputs allow flexibility for different load requirements without needing multiple transformer types. Consider the through-hole package constraints and ensure adequate PCB spacing for the 41.27 mm height profile during layout design.

Part Context

This model belongs to the DPC series of miniature low power transformers manufactured by Signal Transformer.
