Help! Identifying and locating a retailer.

Hi,

Newbie and a complete amateur here.

I’m trying to identify and replace the third inline component on the image from the left. Which looks to be burnt out. I believe it was a short.

The id is ‘4946 bt w56c’ on the fourth, the manufacturer of the board is SG Damp Tronic, but I cannot find any info on a replacement anywhere.

I’m confident I can replace it, but not sure at all about the correct replacement.

Any help would be greatly appreciated!!!

Thanks in advance!
