Six on capacitor charges
The US Department of Justice (DoJ) has accused six people of conspiring to rig the prices charged for capacitors. Prosecutors say that six foreign nationals, all executives with electronics manufacturers, conspired to keep the prices for capacitors artificially high. The six struck a series of deals extending from 2000 to …

Some time ago, I made a similar point, but was told by someone on the forums that the MTBF is based on the device being used at it's maximum voltage and temperature rating.
I was told that if you over-specify the capacitor, for example use ones rated at 105 Centigrade and 1000V for a instance that was room temperature plus and 230V, the MTBF would be exceeded many times.
Of course, what that probably means is that the original designers over-specify the devices, and during the production planning, devices only just exceeding the typical operating environment would be substituted as a cost saving measure.
I'm not really fussed, as it means that broken things with simple fixes can be bought and repaired for my own use, quite cheaply.
I often wonder just how many of the multitude of flat panel TV's that appear in our local recycling center are an easy fix.

Re: @DaLo
Sure the temperature has a significant bearing on extending the lifetime, however it isn't as dramatic as some people have stated. Overall I have seen many caps die, often in power supplies and they are all in 24x7 devices and the caps are on the budget end with relatively low (often 10,000 hours) lifetime ratings.

Re: @DaLo
I recently spent some time learning how modern transformer-less switch-mode power supplies actually operate (thanks BOLTR on youtube), and I've changed my mind about how many of the capacitors are on 24x7 in the power supply.
It is quite clear that there are some that don't, but most power supplies in devices with standby mode nowadays appear to use a basic bridge rectifier and some high quality capacitors, and then feed the barely smoothed 120/240V DC into switched MosFets and smoothing capacitors/voltage regulators to act as voltage converters. The result is that when the device is in standby, most of the caps on the LT side of the MosFets are actually not powered up at all.
Of course, the switching control circuits are powered all the time, as are the first stage smoothing capacitors on the HT side, but this somewhat reduces the need for over-spec'd devices that will run for 100,000s of hours.
I'm not denying that capacitors fail, but I wonder what the statistical variance is on the MTBF figures for the cheapest Chinese capacitors actually is. I suspect this is more likely to cause early failures rather than devices that get close to the MTBF.

I wonder what what's in store for them. Hopefully not discharge without conviction.
The deals seem to have accumulated for quite some time, so I doubt they'll get a plate as a reward. I'm glad the D.o.J. have the spare capacity to deal with them though.
I'm glad its Faraday: time to go home!
(In my defense I'm a touch delirious at present.)

Having been on the discharge end of a 0.1 Fd cap charged to - 20 kV, shocking indeed (farad, not milli- or micro-farad). So far, 9 of us lived (1985). only 2 w/o a pacemaker. [I always kept my linoleum floors washed with detergent, no wax, thank you.)
On a more serious note, I'm far from surprised here. The real surprise would be that such collusion doesn't occur, sadly. Anyone recall the VDT or LCD price-fixing scandals? Especially for military contracts. Don't get me started on those!
Mines the one with military price schedule in it. (No capacitors, please!)

Six foreign companies agreed to fix the prices.
Which is exactly the same that US companies (IBM / Drugmakers) have been doing since the dawn of market capitalism. Only reason these are being put in the dock is they aren't Amurikan.

Re: At least...
One of the female perps, Millie Ohm had originally planned to cut her way out after giving a sine to her boyfriend Henry to meter with some escape equipment, but he was foiled by a SAW filter. So instead she seduced a guard who couldn't resistor, then escaped across the Wheatstone bridge on her megacycle.
