Seems to be a new item carried by Mouser. 2W, 3W, 5W, and 10W available. There's even a double (twin) style. Tons of values (but only a select dozen or so appear to be stocked).
Here's some part numbers for common emitter resistor values (5W only):
0.22 Ohm - 660-BPR58CR22J
0.33 Ohm - 660-BPR58CR33J
0.47 Ohm - 660-BPR58CR47J
1.0 Ohm - 660-BPR58C1R0J
18mm height x 14mm length x 5mm width, 9mm lead pitch, 13mm lead length. 2.5x rated power for 5 seconds to maintain +/-1.0% of initial value. No info on time to destruction.
Cool beans...
