Failed aluminium electrolytic capacitors with open vents in the top of the can, and visible dried electrolyte residue (reddish-brown color) The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, [1] [2] due to faulty electrolyte composition that ...
Phrases used by the tech savvy to mean that a problem is caused entirely by the fault of the user include PEBKAC [8] (an acronym for "problem exists between keyboard and chair"), PEBCAK [9] (an alternative, but similar, acronym for "problem exists between chair and keyboard"), POBCAK (a US government/military acronym for "problem occurs between ...
A stuck sub-pixel or stuck pixel is a pixel that is always "on". [2] This is usually caused by a transistor that is getting power all the time (VA/IPS) or not getting any power (TN) and is therefore continuously allowing light at that point to pass through to the RGB layer. Any given pixel will stay red, blue, or green and will not change when ...
The Roku OS is an operating system software developed by Roku Inc. It has powered consumer electronics products such as Roku-branded streaming players and TVs since 2004. The Roku OS is the most popular TV operating system in the U.S., reaching an estimated 90 million households as of 2025.
1) Values for a typical capacitor with 100 μF/10–16 V Aluminum electrolytic capacitors with non-solid electrolyte are the best known and most widely used electrolytic capacitors. These components can be found on almost all boards of electronic equipment. They are characterized by particularly inexpensive and easy to process base materials.
From 1999 through at least 2010, a stolen recipe for such a water-based electrolyte, in which important stabilizers [47] [48] were absent, [49] led to the widespread problem of "bad caps" (failing electrolytic capacitors), leaking or occasionally bursting in computers, power supplies, and other electronic equipment, which became known as the ...

A typical ceramic through-hole capacitor. A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
