LP-10-250

Power Transformers Overview

The LP-10-250 is a board-mount power transformer from the LP series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC input. The secondary configuration provides 10 VCT at 250 mA and 5 V at 500 mA, delivering a total power rating of 2 VA. Designed for through-hole mounting, it utilizes hum-bucking semi-toroidal construction to minimize electromagnetic interference. The unit operates at standard line frequencies and measures 63.5 mm in length, 50.8 mm in width, and 27.1 mm in height.

Power Transformers Feature Summary

• Hum-bucking semi-toroidal construction reduces electromagnetic interference
• Dual primary winding supports 115 VAC and 230 VAC operation
• Through-hole PCB mounting style for secure installation

Power Transformers Applications

• Servo power supplies
• Low-power electronic control circuits
• General purpose AC to DC conversion stages

Power Transformers Procurement Notes

Verify the specific datasheet version for mechanical tolerances and insulation class requirements before integration. Confirm that the 2 VA rating meets the peak load demands of the target circuit. Ensure the through-hole footprint matches the PCB design guidelines provided by Signal Transformer. Check RoHS compliance status if required by regional regulations.

Power Transformers Selection Notes

Select this component when low-profile board mounting is required alongside noise-sensitive applications. The semi-toroidal design offers a balance between size efficiency and acoustic performance compared to standard laminated transformers. Consider the 2 VA limit when calculating thermal management needs for enclosed environments.

Power Transformers Part Context

This part belongs to the LP series of printed circuit mount transformers. These components are engineered for compact electronics where space constraints and signal integrity are critical. The series typically includes various voltage and current combinations to support diverse low-power industrial and consumer applications.

Power Transformers Replacement Considerations

Direct substitutes must match the 2 VA rating, 115/230 VAC primary, and 10VCT/5V secondary specifications. Verify physical dimensions to ensure compatibility with existing PCB footprints. Alternative brands may require re-validation of mounting hole patterns and lead configurations.
