3FD-448

Power Transformers Overview

The Tamura 3FD-448 is a board-mount power transformer with a 6 VA rating, designed for through-hole installation. It features dual primary windings supporting 115 VAC and 230 VAC inputs, and dual secondary windings providing 24 VAC outputs that can be configured in series for 48 VAC or parallel for 24 VAC. The unit utilizes a laminated core construction and measures 34.54 mm in height. This component belongs to the 3FD series and is suitable for applications requiring isolated AC power conversion with standard PCB pin termination.

Power Transformers Feature Summary

• Dual primary winding configuration for flexible 115 VAC or 230 VAC input selection
• Dual secondary winding design allowing series or parallel output voltage adjustment
• Laminated core structure optimized for efficient power transfer at 6 VA capacity
• Through-hole PC pin termination for secure board mounting

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Consumer electronics utilizing standard AC mains input
• Equipment needing 24 VAC or 48 VAC secondary power rails
• General-purpose board-level power conversion modules

Power Transformers Procurement Notes

Verify compliance with RoHS directives by consulting the manufacturer's detailed documentation. Confirm that the specific orderable part number matches the required electrical specifications and physical dimensions. Ensure that the through-hole footprint aligns with the target printed circuit board layout before finalizing procurement decisions.

Power Transformers Selection Notes

Select this transformer when a 6 VA isolation barrier is required between primary and secondary circuits. The dual winding architecture supports both 24 VAC and 48 VAC output configurations, offering flexibility in system design. Consider the 34.54 mm height constraint during mechanical integration planning to ensure adequate clearance within the enclosure.
