☷ Product Description
The model naming of high-frequency transformers is usually based on the core structure type as the core prefix, and the suffix number represents the size or specification parameters of the core. Different series correspond to differentiated application scenarios and performance characteristics. The following is a classification of mainstream models and key information by magnetic core type: ▶ 1、 EE series (basic universal type) EE type is the most commonly used basic ferrite core structure, with a wide range of applications, covering scenarios such as switching power supplies, LED drivers, and electronic device power supplies. It has the characteristics of easy winding and high cost-effectiveness. • Common models: EE-13, EE-16, EE-19, EE-22, EE-25, EE-28, EE-35, EE-42, EE-50 • Model rule: The larger the suffix number, the larger the magnetic core size (height, center column cross-sectional area), and the higher the upper limit of output power. • Typical applications: EE-13/16 is suitable for small smart home devices, while EE-42/50 can be used for industrial grade switch power supply main transformers. ▶ 2、 PQ series (power intensive) The PQ series has the core advantage of “high power density”, with a compact magnetic core structure and excellent heat dissipation performance. The number represents the length x width size of the magnetic core, and is widely used in power adapters, industrial equipment, etc. Common models: PQ2625, PQ3220, PQ3230 Model Analysis： • PQ2625（26mm×25mm）：Compact size, suitable for smart homes and small frequency converters; • PQ3220（32mm×20mm）：Medium power scenarios, such as LED drivers and small power modules; • PQ3230（32mm×30mm）：High power demand, used for industrial power adapters and high-frequency inverters. ▶ 3、 EFD series (ultra-thin flat type) Specially designed for ultra-thin switching power supplies, using flat ferrite cores, balancing high power and small size, with high requirements for PCB board installation accuracy. • Common models：EFD15、EFD20、EFD25、EFD30 • Application scenarios: Laptop power adapter, ultra-thin LED display power module, portable electronic device power supply. ▶ 4、 ER/EC series (easy winding high-power type) The center column of the magnetic core is cylindrical in shape, with low winding difficulty and large winding cross-sectional area, which can improve output power and is suitable for switching power transformers, blocking coils, etc. Common models： • ER series：ER2510、ER2834、ER3542、ER4042、ER4950 • EC series：EC2820、EC2828、EC34、EC39、EC40、EC49 ▶ 5、 EDR series (high-voltage broadband type) It has a wide operating voltage (3V-1000V) and a wide frequency range (20kHz-500kHz), with a maximum power of up to 3000W. It complies with UL, VDE and other multinational certifications and supports customization. • Common models：EDR20、EDR25、EDR26、EDR28、EDR39、EDR40、EDR2009、EDR2810 • Model Rule：Partial suffix numbers represent installation dimensions, such as the “28” of EDR2810 corresponding to magnetic core height related parameters; • Application Scenarios：Industrial grade high-voltage power supply, high-power DC-DC converter. ▶ 6、 Other mainstream series • ETD series: The magnetic core structure is suitable for high-frequency and high current scenarios. Common models include ETD34, ETD39, ETD44, and ETD50, which can be used in new energy power supply systems; • RM series: miniaturized magnetic core, suitable for low-power signal coupling scenarios, models RM6, RM8, RM10; • POT series: Excellent protection performance, suitable for harsh working conditions, commonly used POT3314, POT3230, POT40; • EPC series: ultra small patch type, used for microelectronic devices, models EPC15, EPC17, EPC19; • EF series: With strong versatility, models EF12.6, EF20, and EF25 are suitable for small audio-visual equipment power supply.
