Dear members,
I have googled for datasheets about transformer EER43X15 22: 4 on the web, but have not found anything. Does anyone know how the wires are drawn in this transformer?
Maybe the "43X15" portion is not a part number, it refers to the size of the ferrite core ( i.e. 43 x 15 mm ) ?
At least one of the windings is wound with multiple strands of wire in parallel, i.e. "Litz" wire, used to counteract the skin effect at high AC frequencies, so I guess this is a specialised and unique transformer out of a switch-mode power supply or inverter. Does the URL on the label lead anywhere? Try Alibaba.
