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
New Techmagazine:
הקטנת הערך של משתנה אחד כפיצוי על שינויים במשתנים אחרים, על מנת לשמור על האמינות. למשל, הקטנת הספק היציאה בטמפרטורות גבוהות
Example sentences:
יצרני הרכיבים מתארים את עקומת הפחתת המאמצים באופן כללי ע"י הקוו היוצא מ-100% מאמץ עד לנקודה של 25 מעלות או במקרה זה עד 70 מעלות ומנקודה זאת המאמץ מופחת עד לטמפרטורה של 155 מעלות (New Techmagazine)
