Description

EI cores are essential components in a wide range of electronic devices, offering efficient and reliable magnetic solutions for various applications. Our EI cores provide superior performance, consistent quality, and excellent value, making them an ideal choice for engineers and designers.

What are EI Cores?

EI cores are laminated magnetic cores constructed from two stacked pieces—an “E” shaped piece and an “I” shaped piece—forming a closed magnetic path. This configuration minimizes leakage flux, leading to higher efficiency and lower power loss compared to other core types. The laminations are typically made from high-quality electrical steel, which minimizes eddy current losses during operation.

Key Features & Benefits:

• High Efficiency: The closed magnetic path significantly reduces magnetic leakage, resulting in higher efficiency and lower energy consumption. This translates to reduced operating costs and improved system performance.
• Low Core Loss: Our EI cores are constructed using high-quality electrical steel with low hysteresis and eddy current losses, minimizing heat generation and improving overall efficiency.
• Excellent Thermal Stability: The lamination design facilitates effective heat dissipation, ensuring stable performance even under high operating temperatures.
• Wide Range of Sizes and Materials: We offer a comprehensive selection of EI core sizes and materials, catering to diverse application needs and requirements. Options include various grades of silicon steel, offering different permeability and loss characteristics.
• Customizable Options: For high-volume projects, we provide custom design and manufacturing services to meet specific specifications, including unique sizes, shapes, and material properties.
• Robust Construction: Our EI cores are built to withstand rigorous operating conditions, ensuring long-term reliability and durability.
