ADH20012

Power Transformers Overview

The ADH20012 is a 1.1VA power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a dual primary winding configuration supporting 115V and 230V inputs in parallel operation at 50/60Hz. The secondary side offers dual windings providing 6.3V in parallel or 12.6V in series configurations. Maximum current ratings are specified as 180mA for the parallel connection and 90mA for the series connection. This component belongs to the AH/ADH series of split bobbin power transformers.

Power Transformers Feature Summary

• Utilizes a split bobbin construction for enhanced isolation performance
• Supports flexible input voltage selection via dual primary windings
• Offers configurable secondary output voltages through parallel or series connections
• Designed for reliable through-hole PCB integration

Power Transformers Applications

• General purpose AC-DC power supply circuits
• Industrial control equipment requiring isolated low-voltage DC
• Consumer electronics with standard mains input requirements

Power Transformers Procurement Notes

Verify the specific datasheet version for the ADH20012 to confirm mechanical dimensions and insulation class ratings prior to design finalization. Ensure that the selected mounting orientation aligns with the thermal management requirements of the host system. Cross-reference the part number with official manufacturer documentation to confirm availability status and lead times, as these factors may vary by region and distributor channel.

Power Transformers Selection Notes

Select this component when a compact 1.1VA isolation transformer is required for mains-powered applications. The dual primary winding allows compatibility with both 115V and 230V regions without changing hardware. Consider the physical size constraints of the PCB layout, as through-hole components require specific hole patterns. Verify that the load current does not exceed the rated 180mA (parallel) or 90mA (series) limits to ensure safe operation and longevity.

Power Transformers Part Context

The ADH20012 is part of the broader AH/ADH series from Zettler Magnetics, which includes various VA ratings such as ADH20016 and ADH20020. These transformers share common design characteristics like split bobbin construction and through-hole termination. The series is engineered for general-purpose power conversion, offering a balance between electrical performance and physical footprint for standard electronic assemblies.

Power Transformers Replacement Considerations

Direct substitutes within the same series include ADH20016 and ADH20020, though these offer different power ratings. When replacing, verify that the new component's VA rating meets or exceeds the original requirement and that the pinout and mechanical dimensions are compatible with the existing PCB footprint.
