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.
breakdown field strength is reduced. Derating curves are included in data sheets for such capacitors. Derating can also provide a safety margin for transient...
cooling capacity has to be derated compared to that of sea level. A rule-of-thumb formula to note: 1 – (h/17500) = derating factor. Where h is the height...
method for derating based upon the type of protector. For earmuffs, the NRR should be derated by 25%, for slow-recovery foam earplugs the derating is 50%...
temperature can reduce the allowable cable power capacity (i.e., less ampacity). Derating refers to the reduction of the ability of a cable to conduct electricity...
recognition for fine-pitch components. There are many techniques of derating. Global derating considers system-wide stops, slow-downs and set ups as well as...
for example, in highly inductive circuits, should be used with a voltage derating. If possible, the voltage profile should be a ramp turn-on, as this reduces...
does not require the same derating that a solid tantalum does and its failure mechanism is open. A 10% to 20% voltage derating curve is recommended for...
conjunction with wiring and raceways has a quantifiable impact upon the ampacity derating, because the thermal insulation properties needed for fire resistance also...
operating temperature and power output. For example, the Latina reactor was derated in 1969 by 24%, from 210 MWe to 160 MWe, by the reduction of operating...
435 hp for take-off, and the 206L-4 is transmission-limited to 495 hp. The derating of the C30P produces an advantage in hot-day and high-altitude operations...
are more stable against oxygen diffusion that results in lower voltage derating rules compared with passivated niobium or tantalum anodes. Electrolytic...
largely unchanged. Power is provided by the CFM56-5A, CFM56-5B, or V2500-A5, derated to 98 kN (22,000 lbf), with option for 105 kN (24,000 lbf) thrust. Airbus...
single-phase switch-mode power-supply loading without any requirement for derating, including all neutral components. Input current distortion remains less...
aircraft is largely unchanged. Power is provided by the CFM56-5A or V2500-A5, derated to 98 kN (22,000 lbf), with option for 105 kN (24,000 lbf) thrust. With...
exposed to surge, peak or pulse currents should be used with a voltage derating up to 70% in highly inductive circuits. If possible, the voltage profile...
Its initial 13,000 km (7,000 nmi; 8,100 mi) range would be followed by derated versions for 8,000 km (4,300 nmi; 5,000 mi). The market was lukewarm as...
500 employees but hardly generated more than 25 MW, even though it had a derated capacity of 60 MW. With a high auxiliary consumption (the energy required...
started in 1992 with the 1,900 lbf (8.5 kN) thrust FJ44-1A. The FJ44-1C is derated to 1,500 lbf (6.7 kN). The uprated to 2,300 lbf (10 kN) FJ44-2A was introduced...
76 kg 7520 2021 Intel Core 11th Gen Tiger Lake U PCH 28w LPDDR4x-3733 (derated from original -4267 after stability issues by BIOS v1.13.0) 32GB (On board)...
losses would exceed 25%. Forced induction effectively eliminates this derating. Some 710 engines have been converted to, or even delivered as, Roots-blown...
to a 25 percent power loss. Turbocharging effectively eliminates this derating. The 645 series has a maximum engine speed of between 900 and 950 revolutions...
arrangement (LAA) engine derating required up to 2134m (7,000 ft) altitude. No high altitude arrangement (HAA) engine derating required up to 4877 m (16...
