2pcs Aluminum Case Resistor 100W 10 Ohm Wirewound Yellow for LED Replacement Converter 100W 10RJ

I used the resistor to load test an ATX PSU and it got super hot. It managed to melt the plastic bag I had it sitting on. Be careful!

work great...

The media could not be loaded.  Installed 4 of these on my 2021 Tundra 3 months ago.

I was planning on using these resistors to dissipate 10 watts. They don't do that very well, even at 1/10 their rating. They are, approximately, the size of a 10W Cermet resistor which means that they don't have the surface area to functionally dissipate much more than about 2-5 watts. They don't have a large base which means they'd be hard pressed to dissipate the 100W they're, supposedly, rated at.I needed to dissipate 10 watts of power (10V @ 1 A). The first resistor I used without a heatsink. It took 2 minutes and 11 seconds for the unit to reach 400F and it kept climbing until at about 410F it opened up, internally and failed.The next unit I place on a heatsink that was, roughly, twice its size. That one took 4-minutes and some seconds and it was operating at slightly over 300F. It opened up when it cooled down.The third unit I placed on a heatsink that was 3x its size. Again, approximately 4-minutes, 300F... opened during cool down and failed.Fourth unit I placed on a heatsink 4x it's size, and placed a fan in front of it. Took approximately 10 minutes to reach 300F. It, too, failed during cooldown. I operated it for 10-minutes.The fifth unit, I never got to... nor the sixth. Three consecutive failures, 60F below the RATED temperature (360F) pretty much made it a worthless game to try to use these units.I'm not sure where the 100W rating came from but it's nowhere near accurate. Even uXcell notes that, for most applications, you need to spec the resistor 30-50% higher than the rating you'd expect it which means they don't trust their products to run to the advertised rating. 100W = 100W not 130 to 150!Long story short, if you're going to use these units for anything that requires reliability they may not be the best choice. Even at 10 watts (1/10 their rated power) these units do not hold up, nor dissipate heat the way that they should.

Couldn’t resist it

Not much else to say. Very high quality resistors.

Wired a pair of these to operate at 50W each to be safe. Confirmed I was operating at 2.2A and these heated up to 300F in just a few minutes and melted the solder joints connecting them together. When I went to remove the spade connector the thing pulled right apart.

Is ok,

Parfait.
