Overview：

Transformers are coupled by magnetic flux linkage, or mutual inductance.

(1) In order to reduce loss, high-frequency transformers often use soft magnetic materials with high permeability and low high-frequency loss as cores.

(2) High-frequency transformers are generally used in small-signal applications, with relatively small size and fewer coil turns.

Mainly used in high frequency switching power supply as high frequency switching power transformer, also used in high frequency inverter power supply and high frequency welding machine as high frequency inverter transformer.

Vertical type and horizontal type is both available for your choice.

Advantages:

1. Could customize product according to your engineer’s basic information.

2. Designed using ferrite core.

3. varnished and 100% full test.

4. Custom inputs and outputs specifications to meet your specific requirements.

5.UL Certificated.

6.Could customize the transformer according to your request.

Size and dimensions:

Magnetic core joints point black ring epoxy adhesive.
