The above is the company's commonly used skeleton style, other styles are not included in the list, welcome to consult. The company can be customized according to customer requirements EFD20 high frequency Transformers of various specifications.
II. Performance of HF Transformers
1. Operating frequency: 20 kHz-500 KHz
2. Output power: 8.0 to 30 W
3. Operating temperature: -40 °C to +125 °C
4. Storage temperature: -25 °C to +85 °C
5. Storage humidity: 30 to 95 %
III. Features of HF Transformers in EFD20
The EFD20 high-frequency Transformer has the characteristics of small size, low height, cheap price and high reliability. EFD Transformer is a high-frequency Transformer designed to adapt to ultra-thin switching power supply. It has a flat ferrite core. Its shape can meet the requirements of the high power of the power transformer and the requirements of the ultra-thin volume. It can also meet the requirements of the switching power supply in terms of temperature rise, but the requirements for the PCB board will be improved. Other properties are close to EE and EC Transformers.
IV. Application of EFD20 high frequency Transformer
EFD20 high-frequency Transformers are commonly used in DC-DC converters, drive Transformers, digital cameras, booster Transformers, and hand-held switch power charger.
V. EFD20 high frequency Transformer price
The price range of the EFD20 high-frequency Transformer is generally between 2.0-3 .5 yuan(RMB). The price mainly depends on the complexity of the product, the customer's requirements for raw materials, and whether or not it requires safety certification.
