Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure compatibility with required voltage configurations. Confirm that the wire lead length and gauge meet the installation requirements. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the chassis mounting hole pattern matches the design specifications before finalizing the order.

Selection Notes

Select this model when a compact toroidal form factor is required for 50 VA applications. Choose the 1182J18 specifically for its ability to support both 117 VAC and 234 VAC primary inputs without rewiring. Consider the dual secondary options if variable voltage outputs are needed from a single transformer unit. Verify that the physical footprint fits within the available enclosure space.

Part Context

This component belongs to the Hammond 1182 series of toroidal transformers, which are designed for industrial and commercial applications. The series offers various power ratings and voltage configurations. The 1182J18 represents a mid-range power option within this lineup, balancing size and performance for standard control and signal processing tasks.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. When replacing, ensure the new transformer matches the 50 VA rating, 117/234 VAC primary input, and 18V/36V secondary output capabilities. Verify dimensional compatibility for chassis mounting.
