34-265-LPI

Power Transformers Overview

The Signal Transformer 34-265-LPI is a semi-toroidal power transformer designed for board mounting via through-hole technology. It features dual primary windings supporting 115V and 230V inputs at 50/60 Hz frequencies. The secondary configuration offers parallel operation at 17V with a 530 mA current rating, or series operation at 34V with a 265 mA rating. The unit has a total power rating of 9 VA and utilizes an encapsulated laminated core construction to ensure electrical isolation and mechanical stability in standard power supply applications.

Power Transformers Feature Summary

• Semi-toroidal encapsulated design for compact board integration
• Dual primary winding capability for versatile voltage input selection
• Configurable secondary output allowing parallel or series connection modes

Power Transformers Applications

• General purpose AC to DC power supply units
• Industrial control system power modules
• Consumer electronics internal power adapters

Power Transformers Procurement Notes

Verify the specific datasheet version prior to ordering, as specifications may vary by production batch. Confirm that the required lead time aligns with project schedules, noting potential delays associated with custom manufacturing cycles. Ensure the through-hole mounting style matches the target PCB layout dimensions and thermal requirements for proper installation.

Power Transformers Selection Notes

Select this component when a compact semi-toroidal form factor is required alongside dual primary voltage flexibility. The configurable secondary winding allows designers to optimize for either higher current at lower voltage or higher voltage at reduced current. Ensure the 9 VA power rating sufficiently covers the load requirements of the downstream circuitry while maintaining appropriate thermal margins.

Power Transformers Part Context

This part belongs to the Signal Transformer line of standard power transformers, specifically engineered for surface mount and through-hole applications. The 34-265-LPI model represents a semi-toroidal variant within their portfolio, offering a balance between magnetic efficiency and physical footprint. It serves as a fundamental isolation component in low-power electronic systems requiring reliable AC voltage transformation.

Power Transformers Replacement Considerations

Direct substitutes must match the 9 VA rating, semi-toroidal shape, and dual primary/secondary winding configurations. Verify that alternative components support the same 115V/230V primary inputs and 17V/34V secondary outputs. Ensure the replacement maintains through-hole mounting compatibility and similar encapsulation standards for equivalent environmental protection.
