F12-2850

Overview

The Triad Magnetics F12-2850 is a split bobbin power transformer designed for PC board mounting. It features a single primary winding rated for 115V AC input. The secondary configuration provides dual outputs: 6.3V DC at 5.7A in parallel and 12.6V DC at 2.85A in series. The unit has a power rating of 36W, utilizes a laminated core, and measures 66.68 mm in length with a width of 55.55 mm.

Feature Summary

• Split bobbin design for nonconcentrically wound windings to reduce leakage inductance
• PC board mount construction for direct integration into printed circuit assemblies
• Dual secondary voltage options supporting both parallel and series connection modes

Applications

• Power supply circuits requiring isolated AC-to-DC conversion stages
• Audio equipment utilizing split-rail or dual-voltage transformer architectures
• Industrial control systems needing compact PCB-integrated isolation transformers

Procurement Notes

Verify the specific secondary current ratings against your load requirements, as the parallel and series configurations offer different amperage capabilities. Confirm that the physical dimensions fit within your enclosure constraints. Ensure the mounting style aligns with your assembly process. Check for any required safety certifications relevant to your target market before finalizing procurement.

Selection Notes

Select this component when a compact, PCB-mountable transformer with dual secondary voltage options is required. The split bobbin architecture is suitable for applications demanding reduced electromagnetic interference. Consider the 36W power rating to ensure adequate capacity for your specific load profile without exceeding thermal limits.
