EI28 High frequency transformer

Product Description

EI28 high-frequency transformers are used in self-excited oscillation electronic transformers, car power audio transformers, switch power drive transformers, mobile equipment transformers, etc.

1. Operating frequency: 20KHz-300KHz

2. Output power: 5 to 30W

3. Working temperature: -40 ° C to+125 ° C

4. Storage temperature: -25 ° C to+85 ° C

5. Storage humidity: 30 to 95%

The characteristics:

The transformer core is made of PC40 and PC44 materials, which have low magnetic loss and a wide operating frequency range of 20-500KHZ;
The column in the transformer skeleton is square, and the coupling between the winding and the magnetic core may be poor. The output efficiency of the transformer itself is not high, but it has cost advantages
Suitable for flyback topology structures, mainly used for small and medium power outputs
Can be used to design transformers and also to make inductors
It can also achieve compliance with safety regulations
Diversified installation methods, including vertical and horizontal options
More suitable for designing with fewer output methods
