Power Transformers Procurement Notes

Verify the specific datasheet version from Signal Transformer or authorized distributors to confirm current manufacturing status and compliance certifications. Ensure the selected variant matches the required secondary configuration (parallel vs. series) and lead length specifications before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when a compact, semi-toroidal form factor is required for 50/60 Hz applications. The dual primary design simplifies inventory management for global markets. Consider the 2.5 VA limit and ensure the load does not exceed 170mA in parallel mode to maintain performance within the specified thermal class.

Power Transformers Part Context

This part belongs to the Signal Transformer LPI series of semi-toroidal power transformers. These components are engineered for high reliability in space-constrained environments. The series typically utilizes epoxy encapsulation for environmental protection and mechanical durability during standard assembly processes.

Power Transformers Replacement Considerations

Direct substitutes must match the 2.5 VA rating, 115/230V primary, and 15V/30V secondary outputs. Verify that replacement parts maintain the same semi-toroidal footprint and through-hole pin spacing to ensure board compatibility without redesign.
