Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to ensure compatibility with required insulation classes and regulatory standards. Confirm that the wire lead lengths and gauge meet the mechanical constraints of the target assembly. Check for RoHS compliance status if environmental regulations apply to the end product deployment.

Selection Notes

Select this model when a 12.6V center-tapped output is required from a standard 115V line. Ensure the load current does not exceed 0.5A to prevent overheating. Consider the chassis mounting style and available space relative to the component's physical footprint. Verify that the operating environment temperature remains within the specified -0°C to +130°C range for reliable operation.
