http://dynapowerusa.com/what-is-output-power-derating/ WebResistor Power ratings are normally specified at +25 o C and must be reduced as the resistor temperature increases. A derating chart is often used, with derating starting at 70 o C [Resistor Derating Curve above]. Since parameters are application dependent, power de-rating curves or charts should be considered general rather than absolute, and only used …
In electronics, derating is the operation of a device at less than its rated maximum capability to prolong its life. Typical examples include operations below the maximum power rating, current rating, or voltage rating. See more Power semiconductor devices have a maximum power dissipation rating usually quoted at a case temperature of 25 °C (77 °F). The datasheet for the device also includes a derating curve which indicates how much a device … See more All dimmers rely on heat conduction and convection to keep the electronic components cool.
