A Capasitor (the purposely misspelling of Capacitor) is a faulty
electrolytic capacitor that fails in a short period of time (1-3years). Most Capasitors are the result of incorrect
electrolyte formulation in aluminum electrolytic capacitors.
Its rumored the "S" in Capasitor is from "Shitty" and like the wrong formula was simply stuck in there .
A
electrolytic Capacitor that explodes instantly from being installed backwards is not a Capasitor, as that is a install error and not a component manufacturing problem.
The Capasitor plague was a period between 1999 and 2007 when Capasitors were killing in a large number of products.
