EE13 Transformer

Providing with quality and standard customer-made electronic and passive components ee13 transformer and solution products, Fullstar Electronics is a leading ee13 transformer manufacturer and supplier in China. welcome to wholesale electronics ee13 transformer from our factory.

An EE13 transformer is a small, high-frequency switching power supply transformer commonly used in electronic circuits. Its name comes from its core component-the E-shaped ferrite core-where "EE" indicates two E-shaped cores are mated together, and "13" represents that the width of the core's center leg is approximately 13 mm.

⚙️ Key Features & Parameters

• Compact Size: The overall dimensions of an EE13 transformer are typically around 14.0mm × 13.0mm (Length × Width), with a maximum height usually within 13.5mm. This makes it ideal for compact electronic devices where PCB space is limited.
• Power Range: It is designed for low-power applications. The power handling capability is closely related to the operating frequency. For example, it can typically handle about 3.1W at 100kHz, and over 9W at 300kHz.
• Operating Frequency: Built for high-frequency switching circuits, it generally operates efficiently within a frequency range of 20kHz to 500kHz.
• Mounting Styles: Depending on the bobbin and pin design, it mainly comes in two mounting styles: Vertical and Horizontal, allowing engineers flexibility in PCB layout.

💡 Core Advantages & Applications

The EE13 series typically uses high-quality MnZn (Manganese-Zinc) ferrite cores, which offer high magnetic permeability and extremely low high-frequency losses. This gives it significant advantages such as high conversion efficiency, minimal heat generation, stable electrical output, and well-controlled leakage flux.

Due to its small footprint and high efficiency, the EE13 transformer is widely used in:

• AC/DC Power Adapters (e.g., phone chargers)
• Small Switching Power Supplies
• DC-DC Converters

Control power boards for various small home appliances and consumer electronics.

📝 Selection & Design Tips

It is important to note that "EE13" is just a standard specification for the core and bobbin size. In practical applications, specific electrical parameters vary greatly depending on the manufacturer and the end product's requirements.

When selecting or replacing an EE13 transformer, you must verify more than just the physical size. Always double-check the custom-designed specifications, including:

• Pin configuration (e.g., 3+2 Pin, 5+5 Pin)
• Turns ratio (Primary : Secondary)
• Inductance value (e.g., 1.35mH, 1.56mH)
• Output voltage and current ratings
