- ER28 core structure for magnetic performance
- Through-hole termination style
Applications
- Main power transformer circuits
- Pulse signal transmission in power supplies
Procurement Notes
Verify availability status carefully as this component is listed as obsolete or discontinued across major distributors. Sourcing may require checking secondary market suppliers or existing stock from previous production runs. Confirm end-of-life notices with the manufacturer before finalizing design-in decisions to ensure long-term supply chain stability.
Selection Notes
Consider the horizontal form factor and 12-pin THT layout when evaluating board space constraints. Since the part is obsolete, assess whether newer generations from the same series offer compatible pinouts and electrical characteristics to facilitate a direct replacement without significant redesign efforts.
Part Context
This component belongs to the Eaton Electronics pulse transformer portfolio, specifically targeting main power conversion stages. The ER28 package size indicates a medium-power application range compared to smaller surface-mount alternatives. It represents a legacy through-hole solution often found in industrial or high-reliability power electronics designs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
