This horizontal high-frequency transformer adopts EE14 ferrite core and has a primary inductance of up to 780mH. Its core feature is optimized for high-voltage input, low-power high-frequency switching power supplies (such as flyback topology); High inductance values can significantly reduce no-load losses and magnetizing currents, thereby improving conversion efficiency. The compact horizontal structure not only saves PCB vertical installation space, but also enhances mechanical stability and heat dissipation performance, making it very suitable for low-power electronic devices such as mobile phone chargers and LED drivers that require high efficiency and miniaturization.
Function
The core function of this component is to serve as the core magnetic element for energy conversion and transfer in high-frequency switching power supply circuits, while achieving electrical isolation between input and output.
Specifically, its main functions include:
1. Energy transmission: Efficiently transfer electrical energy from the primary winding to the secondary winding through magnetic field coupling.
2. Voltage conversion: By adjusting the turns ratio of the primary and secondary windings, the voltage can be raised or lowered to achieve the desired output voltage for the design.
3. Electrical isolation: Establish a safe insulation barrier between the input (high voltage) and output (low voltage) to prevent high voltage from entering the low voltage end, ensuring the safety of users and equipment and meeting safety regulations.
4. Impedance matching: Implementing impedance transformation in the circuit to ensure that power can be effectively transmitted from the power source to the load.
| Feature Category | Performance Characteristic | Description & Implication |
| Electrical Performance | High Primary Inductance (780mH) | Extremely high inductance value minimizes magnetizing current, leading to very low core losses and high efficiency at high input voltages, especially under light or no-load conditions. |
| High-Frequency Operation | Utilizes a Mn-Zn Ferrite core optimized for operation in the kHz to hundreds of kHz range (e.g., 40-200 kHz) with low core loss (low hysteresis & eddy current losses). | |
| Isolation Voltage | Provides high electrical isolation between primary and secondary windings, meeting safety standards (like UL, CE) and protecting low-voltage circuits. | |
| Saturation Current (Isat) | Expected to be very low (typically a few mA). This is a critical design constraint. The operating peak current must remain well below Isat to prevent core saturation and failure. | |
| Physical & Construction | Horizontal (Low-Profile) Package | Pins are bent 90 degrees for surface-mount (SMD) or low-profile through-hole mounting. Saves vertical space and improves mechanical stability on the PCB. |
| Standard EE14 Core | Industry-standard core size (center leg approx. 14mm wide). Offers a good balance of compact size, cost-effectiveness, and reliable performance for low-power applications. | |
| Core Material | Ferrite (Mn-Zn). Chosen for its high resistivity and excellent magnetic properties at high frequencies. | |
| Thermal Performance | Operating Temperature Range | Typically rated for an ambient temperature range of -40°C to +125°C (or +85°C to +130°C, depending on insulation class). Specific rating must be checked in the datasheet. |
| Thermal Management | The horizontal design often allows for better heat dissipation into the PCB through the pins and via the large surface area in contact with the board. | |
| Application-Specific | Typical Topology | Primarily designed for Flyback Converters, the most common topology for low-power, isolated SMPS. |
| Power Rating | Suitable for low-power applications, typically in the range of 3W to 10W. | |
| Key Application | Ideal for high-input voltage, low-output power scenarios such as: | |
| • AC/DC Adapters/Chargers (phone, router) | ||
| • LED Driver Modules | ||
| • Auxiliary/Standby Power Supplies (in larger appliances) | ||
| • **Isolation DC-DC Converters |
