24-100-LPI

Power Transformers Overview

The Signal Transformer 24-100-LPI is a semi-toroidal power transformer designed for through-hole PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation in parallel configuration. The secondary side offers two output configurations: a parallel winding providing 12 VAC at 200 mA, and a series winding providing 24 VAC at 100 mA. This component has a power rating of 2.5 VA and utilizes a leaded construction suitable for standard industrial electronics applications requiring isolated AC voltage transformation.

Power Transformers Procurement Notes

Verify the specific secondary configuration required for your circuit design, as the part supports both parallel (12V) and series (24V) outputs. Confirm that the 2.5 VA power rating meets the load demands of your application. Ensure the physical dimensions are compatible with the PCB layout and enclosure constraints. Check for any RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Power Transformers Selection Notes

Select this model when a compact semi-toroidal form factor is needed for low-power isolation. Choose between parallel or series secondary connections based on the target voltage and current requirements of the downstream circuitry. Consider the thermal performance and ambient operating temperature range during system integration. Evaluate the mechanical stability provided by the through-hole leads against vibration or shock conditions in the final assembly environment.

Power Transformers Part Context

This component belongs to the Signal Transformer semi-toroidal power transformer series, which focuses on space-efficient designs for general-purpose power conversion. These transformers typically bridge the gap between standard laminated cores and full toroidal shapes, offering improved efficiency over rectangular cores while maintaining easier mounting than complete toroids. The series is widely used in applications where size constraints limit the use of larger traditional transformers.

Power Transformers FAQ

Can the secondary windings be used simultaneously?

Yes, the transformer provides separate secondary windings that can be configured independently for parallel (12V/200mA) or series (24V/100mA) operation depending on the circuit design.

What is the maximum power rating of this transformer?

The maximum power rating is 2.5 VA, which limits the total energy transfer capability under continuous operating conditions.
