WUXI WEIBANG TRANSFORMER MANUFACTURE CO.

C core is made of Hi-B oriented silicon steel strip. C core is assembled by 2 U shape cores, and there is a gap between two U shape cores. C core is also called the cut core because it looks like a rounded rectangle cut at the center. The air gap is not always bad for transformers. Sometimes it does good. C core is good at making choke and audio output transformer, because of it's adjustable air gap. Certain air gap can reduce the flux saturation.
Easily assembled
Prepare 2 coils and insert the core. That is simple. There is no need to insert EI laminations one by one like EI transformer.
Air gap adjustable
The air gap in C core can be adjusted as you wish to make different applications. It is suitable to make choke and audio output transformer.
