Overview
The F-378P is a laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V AC input. The secondary configuration provides a center-tapped output of 56.0V at 0.42A, with an alternative 28.0V rating available. The unit has a maximum power capacity of 24VA and includes 1500Vrms isolation voltage. It utilizes PC pin termination for board installation.
Feature Summary
- Dual primary winding design supporting 115V and 230V AC operation
- Center-tapped secondary output providing 56.0V at 0.42A
- High isolation voltage rating of 1500Vrms
- Laminated core construction for efficient power transformation
Applications
- Industrial control systems requiring isolated power
- Medical equipment power supplies
- General-purpose AC to DC conversion circuits
- Audio amplifier power stages
Procurement Notes
Verify the specific secondary voltage requirement (56.0V vs 28.0V) against your circuit design before ordering. Confirm that the through-hole PC pin package matches your PCB footprint. Ensure the 24VA power rating meets the load demands. Check RoHS compliance status if required for your manufacturing process. Validate the 1500Vrms isolation specification against safety standards applicable to your end product.
Selection Notes
Select this component when a compact, board-mountable transformer with high isolation is needed. The dual primary allows flexibility for different regional line voltages. Consider the physical dimensions and weight constraints of your enclosure. Compare the 24VA limit against peak current surges in your application to prevent saturation. Evaluate thermal management requirements based on the laminated core efficiency.
Part Context
This part belongs to Triad Magnetics' standard power transformer lineup, characterized by laminated cores and through-hole packaging. It serves as a fundamental component for converting mains voltage to lower AC levels suitable for rectification. The series is widely used in applications where space is limited but robust isolation is critical.
Replacement Considerations
Hammond Manufacturing 160H40 is listed as a similar replacement option.
