Overview
The DST4-12B6 is a laminated core power transformer manufactured by Pulse Electronics. It features a split bobbin design and is intended for through-hole mounting. The primary winding supports parallel operation at 115V or 230V input voltages. Secondary outputs are configurable in parallel for 6.3V at 1A maximum current, or in series for 12.6V at 500mA maximum current. The unit has a 6VA rating and complies with RoHS standards.
Feature Summary
- Laminated core construction with open-style split bobbin design
- Configurable secondary voltage output via parallel or series connection
- Through-hole terminal style for standard PCB integration
- RoHS compliant manufacturing process
Applications
- Low frequency power supply circuits
- General purpose AC to DC conversion stages
- Industrial control equipment power modules
Procurement Notes
Verify the specific datasheet version from Pulse Electronics to confirm insulation class and thermal characteristics. Ensure the application circuit matches the parallel or series secondary configuration requirements. Check for any regional regulatory compliance updates prior to final procurement.
Selection Notes
Select this component when a 6VA isolation transformer is required for mains frequencies. The choice depends on the need for dual secondary windings allowing flexible voltage selection between 6.3V and 12.6V. Through-hole mounting is necessary if surface mount alternatives are unsuitable for the mechanical constraints.
Part Context
This part belongs to the low-frequency laminated transformer family from Pulse Electronics. It utilizes traditional wound core technology rather than ferrite cores, making it suitable for standard line frequencies. The split bobbin architecture aids in manufacturing consistency and electrical isolation performance.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching VA rating, primary voltage, and secondary configuration capabilities.
