VTX-121-3832-409

Overview

The Vigortronix VTX-121-3832-409 is a laminated core power transformer designed for PCB mounting. It features dual primary windings rated for 115V and 230V operation in parallel configuration, and dual secondary windings providing 9V outputs that can be connected in series to achieve 18V. The unit has a power rating of 3.2VA at 50/60Hz frequencies. It utilizes an encapsulated construction method for environmental protection and mechanical stability.

Feature Summary

• Encapsulated construction for enhanced durability
• Dual primary winding design for flexible voltage input
• Dual secondary winding configuration allowing series or parallel output options

Applications

• General purpose electronic equipment power supplies
• Control circuit isolation
• Low power AC signal transformation

Procurement Notes

Verify the specific pinout and physical dimensions against your PCB footprint before ordering. Confirm that the 3.2VA rating meets the load requirements of your application. Ensure the operating temperature range aligns with your device's thermal environment. Check for any specific regulatory compliance markings required for your target market.

Selection Notes

Select this component when a compact, encapsulated transformer is needed for low-power applications requiring 9V or 18V secondary outputs. The dual primary design offers flexibility for international voltage standards. Consider the thermal class B rating for standard ambient temperature environments. Evaluate space constraints as encapsulated transformers may have larger footprints than open-frame equivalents.

Part Context

This part belongs to the Vigortronix VTX series of PCB-mounted transformers. These components are characterized by their encapsulated epoxy resin housing, which provides insulation and protection against moisture and vibration. The series typically includes various power ratings and voltage configurations to suit different low-power electronic designs.

Replacement Considerations

Direct replacements must match the 3.2VA rating, 115V/230V primary configuration, and 9V secondary output capability. Verify that substitute parts maintain the same encapsulation style and PCB mounting compatibility. Cross-reference datasheets for identical electrical parameters and physical dimensions to ensure seamless integration.
