70010K

Power Transformers Overview

The Talema Group LLC 70010K is a toroidal power transformer with a 3.2VA rating. It features dual 115V primaries configurable for parallel or series connection to support 115V or 230V input. The secondary provides dual 7V outputs, allowing for parallel (458mA) or series (14V, 229mA) configurations. Designed for through-hole mounting, this component utilizes a low-profile PCB mounting style typical of the 70000K series.

Power Transformers Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary windings enabling flexible voltage input selection
• Dual secondary windings supporting multiple output voltage and current configurations
• Through-hole mounting design for secure PCB integration

Power Transformers Applications

• Low-power AC power supply circuits
• Electronic equipment requiring isolated DC power rails
• Audio amplifiers and signal processing units
• Control systems utilizing low-voltage AC inputs

Power Transformers Procurement Notes

Verify the specific datasheet version when ordering, as Talema may update pinout diagrams or insulation ratings without changing the base model number. Confirm that the required secondary configuration (parallel vs. series) matches the application's voltage and current needs before procurement. Ensure the through-hole footprint aligns with the PCB layout specifications provided in the official documentation.

Power Transformers Selection Notes

Select this model when a compact toroidal transformer is needed for 3.2VA applications. Consider the 70000K series characteristics if low profile and weight are critical constraints. Evaluate whether the available secondary voltages meet the load requirements directly or if additional regulation is necessary. Check thermal limits against the operating environment temperature.

Power Transformers Part Context

This component belongs to the Talema 70000K series, which specializes in low-profile PCB mounting toroidal transformers. The series ranges from 1.6VA to 50VA, offering various power levels while maintaining a small form factor. The 70010K represents the lower end of this power range, suitable for lightweight electronic designs.

Power Transformers Replacement Considerations

Direct replacements must match the 3.2VA rating, toroidal construction, and dual 7V secondary configuration. Verify that substitute parts support the same primary voltage options and through-hole mounting style. Cross-reference electrical parameters such as insulation class and operating temperature range to ensure compatibility.
