3FD-436

Power Transformers Overview

The Tamura 3FD-436 is a board-mount power transformer featuring a laminated core and through-hole termination. It supports primary voltages of 115 VAC and 230 VAC with dual winding options. Secondary outputs include 18V at 340mA in parallel configuration or 36V at 170mA in series configuration. The unit has a 6VA power rating, operates at 50/60Hz, and provides 2500VRMS isolation. Dimensions are approximately 41.5mm x 34.8mm x 36.2mm.

Power Transformers Feature Summary

• Dual primary winding design for flexible voltage input
• Configurable secondary output for parallel or series operation
• High isolation voltage rating for safety compliance

Power Transformers Applications

• AC to DC power supply units
• Industrial control systems
• Consumer electronics power stages

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and insulation class requirements. Ensure the selected pin configuration matches the target PCB footprint. Check RoHS compliance status if environmental regulations apply to the final assembly. Confirm thermal performance under maximum load conditions before integration.

Power Transformers Selection Notes

Choose this component when a 6VA isolated power stage is required with standard through-hole mounting. The dual secondary winding allows flexibility between higher current/lower voltage or lower current/higher voltage needs. Verify that the physical dimensions fit within the enclosure constraints. Consider the operating temperature range relative to the application environment.

Power Transformers Part Context

This part belongs to the Tamura 3FD series of general-purpose power transformers. The series offers various power ratings and voltage configurations for AC line applications. These components are designed for reliable operation in standard industrial and commercial environments.

Power Transformers Replacement Considerations

Cross-reference with other 3FD series variants such as 3FD-410 or 3FD-424 if different power ratings are needed. Ensure any substitute maintains the same 2500VRMS isolation and through-hole termination style.
