TT Electronics (irctt.com) might be the manufacturer. They have SQM and CVF
series resistors but a search for SQF turns up nada:

irctt.com/file.aspx?product_id=305&file_type=datasheet

For what it's worth the markings are not similar at all. (I find that
manufacturers like to stick with similar font and color and such.)

The internal fuse is clearly labeled 10A and 185c. Not sure if this means
it's only a thermal fuse rated at a maximum of 10A or it's a current fuse
rated at a maximum of 185c or if it's a thermal and current fuse.

Either way it's apparently more than just a resistor.

Suggestions?

Thanks.
