Derating - Wikipedia

WebResistors, LEDs, Other Diodes, Capacitors, ICs, CPUs. Another common word for derating, in the context of computers and CPUs, is underclocking. As opposed to overclocking, where you run a cpu at a higher than rated speed, underclocking (aka derating) runs it at a lower speed, allowing for less heat and longer life. WebApr 28, 2016 · For reliability we then derate that power by 50%, so the effective rating of the part in this environment is about 30% of the nominal rated power. Note that even at that derating value, it still forms part of the reliability analysis (usually done to MIL-HDK-217). flocking gun for christmas trees
