DPC-40-20

Overview

The DPC-40-20 is a laminated core power transformer manufactured by Signal Transformer, designed for printed circuit board mounting. It features dual primary windings supporting 115V and 230VAC parallel operation and a secondary configuration providing 20V at 40mA or 40VCT at 20mA. With a maximum power rating of 1VA, this component utilizes through-hole termination for secure PCB integration.

Feature Summary

• Dual primary winding design enables compatibility with both 115V and 230VAC input sources via parallel connection.

Applications

• Low-power electronic circuits requiring isolated AC voltage conversion
• Printed circuit board mounted power supplies
• Control transformers in industrial equipment

Procurement Notes

Verify the specific secondary configuration required for your application, as the part number denotes a standard output that may vary in tap availability depending on the manufacturer's current production batch. Confirm mechanical footprint compatibility with your PCB layout before ordering. Ensure input voltage specifications match the dual primary winding capabilities to prevent operational failure.

Selection Notes

Select this transformer when a compact, low-power solution is needed for PCB-mounted applications. The dual primary winding allows flexibility for global voltage standards. Consider the 1VA power limit and ensure the load current does not exceed 40mA for the 20V output or 20mA for the 40VCT output to maintain performance and thermal safety.

Part Context

This component belongs to the DPC series of printed circuit power transformers from Signal Transformer. These units are characterized by their small form factor and laminated core construction, intended for direct soldering onto circuit boards. They serve as essential isolation components in various low-voltage power distribution systems.

Replacement Considerations

Direct substitutes include other Signal Transformer models within the DPC series that share identical electrical ratings and mounting dimensions. Verify pinout compatibility and physical size constraints when considering alternative manufacturers' equivalents to ensure seamless integration into existing designs.
