3FS-316

Power Transformers Overview

The Tamura 3FS-316 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated for 115 VAC and dual secondary windings providing 8 VAC or 16 VAC configurations. The unit has a total power rating of 2.4 VA, with secondary current ratings of 300 mA in parallel mode and 150 mA in series mode. The component measures 32.1 mm in height and utilizes PC pin termination for secure board connection.

Power Transformers Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Dual secondary winding capability supporting parallel or series voltage configurations
• Through-hole mounting style with PC pin termination for reliable PCB integration

Power Transformers Applications

• General purpose AC to AC voltage transformation in electronic circuits
• Power supply stages requiring isolated low-voltage outputs
• Industrial control systems utilizing standard through-hole assembly processes

Power Transformers Procurement Notes

Verify the specific datasheet version for the 3FS-316 to confirm compliance with current RoHS and REACH standards. Ensure that the required isolation voltage meets the safety requirements of the target application. Cross-reference the physical dimensions against the printed circuit board layout to guarantee adequate clearance and mechanical fit during installation.

Power Transformers Selection Notes

Select this component when a 2.4 VA capacity is sufficient for the load requirements. The 115 VAC primary input must align with the available line voltage. Consider the dual secondary options if both 8 VAC and 16 VAC flexibility is needed within a single design. The through-hole format is suitable for applications prioritizing mechanical robustness over surface area constraints.

Power Transformers Part Context

This transformer belongs to the Tamura 3FS series of power transformers. The series offers various power ratings and voltage combinations tailored for different industrial and commercial applications. The 3FS-316 specifically addresses needs for moderate power isolation with flexible secondary output options using a standard laminated core architecture.
