Overview
The AEE25-3971 is a flyback transformer manufactured by Allied Components International, designed for switching mode power supply applications. It utilizes an EE25 core configuration with a ten-pin through-hole mounting style. The component features a primary inductance of 3.4mH and supports a high isolation voltage rating of 3000VAC. It is constructed to meet RoHS compliance standards and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Supports flyback topology for efficient energy transfer in switching converters
- Provides robust electrical isolation via a 3000VAC dielectric strength rating
- Utilizes a compact EE25 core structure optimized for vertical or horizontal PCB integration
Applications
- Switching Mode Power Supply (SMPS) designs
- Flyback converter circuits
- General purpose AC/DC adapter implementations
Procurement Notes
Verify the specific datasheet version prior to ordering, as manufacturing revisions may alter pin assignments or mechanical dimensions. Confirm that the 3.4mH primary inductance aligns with the target circuit requirements. Ensure the 3000VAC isolation rating meets safety regulatory standards for the intended end-use environment.
Selection Notes
Select this component when a 3.4mH primary inductance is required for EE25 form factor transformers. Consider the 3000VAC isolation capability for applications demanding high voltage separation between primary and secondary sides. Evaluate the ten-pin through-hole package against available PCB footprint constraints and assembly methods.
Part Context
This part belongs to the Allied Components AEE25 series, which encompasses various EE25 core transformers. These components are standardized for use in low to medium power switching applications. The series offers multiple variants differentiated by inductance values and winding configurations while maintaining consistent mechanical footprints.
Replacement Considerations
Cross-reference with Allied Components models such as AEE25-4071 or AEE25-4019 if different inductance or isolation ratings are acceptable. Verify compatibility with existing PCB layouts before substituting.
