Definition from
Martek Power Abbott, Inc.:
Reducing one operating parameter to compensate for changes in other parameters to maintain reliability. For example, the reduction in output power at elevated temperatures.
Example sentences:
Two things can be inferred from these ratings: the maximum storage temperature is equal to the derated temperature. Also, the slope of the derating can be used to calculate an equivalent thermal resistance in degrees C per watt. The difference between the no-load and maximum full load temperature is less than or equal to the temperature rise at full load. (P-N Designs, Inc.)
Most dc/c manufacturers have design-derating guidelines, but sometimes designers use guidelines they have developed themselves. As engineers, we derate components to improve their reliability by decreasing component stress. (Hearst Business Communications, Inc)
A derating chart is often used, with derating starting at 70oC. Since parameters are application dependent, power de-rating curves or charts should be considered general rather than absolute, and only used as a guideline. (interfacebus.com)

Definition from
own experience or research:
Derating is the technique employed in power electrical and electronic devices wherein the devices are operated at less than their rated maximum power dissipation taking into consideration the case/body temperature, ambient temperature and the type of cooling mechanism used.
Example sentences:
οι ηλεκτρονικές συσκευές έχουν μέγιστη απόδοση σε κάποια θερμοκρασία. Όσο η θερμοκρασία αυξάνεται η απόδοση ελαττώνεται δηλαδή η ικανότητά τους υποβιβάζεται π.χ. αν ένα εξάρτημα έχει 100watt απόδοση στούς 25C στούς 65C θα έχει 40watts απόδοση. (wikipedia)

hDerating μεταφράζεται ως υποβιβασμός ικανότητος και μείωση απόδοσης Λεξ.Πανταζή. Σε μία συσκευή μπορείς να πης για απόδοση στα ηλεκρονικά κυκλώματα όμως όπως transistor capacitors κλπ όχι Δες εδώ ttp://en.wikipedia.org/wiki/Worst-case_circuit_analysis
