Since I'm an electrical engineer and have two "identical" parts, I made a comparison between the parts and their respective properties. Both parts passed the test well, but one seemed more than 10 times better than the other. By "better" I mean that the series resistance (which dissipates the power and heats up the part) was exceptional on the one hand and good on the other. This is very unusual for parts from the…
