EE13/7/4 Horizontal
INF
The EE13 horizontal flyback transformer is a compact and efficient magnetic component engineered for offline switch mode power supply (SMPS) applications. Designed with a ferrite EE13 core structure, it enables stable energy transfer under high-frequency switching conditions, making it an ideal solution for low-power AC-DC conversion systems.
Built to operate across a broad temperature range, the EE13 flyback transformer maintains consistent electrical performance even under demanding conditions. It is suitable for both fixed-frequency and quasi-resonant topologies, providing flexibility for various circuit designs. Additionally, multiple output configurations can be customized to meet specific application requirements.
Typical applications include power adapters, battery chargers, LED drivers, smart home devices, and auxiliary power modules in consumer electronics and industrial control systems. Thanks to its small footprint and high reliability, this transformer is widely used in modern compact power solutions.
