capacitor plague

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

くだけた表現 不可算名詞

(electronics, informal) Premature failure of an electrolytic capacitor, especially when several are beginning to fail at the same time in a piece of equipment (due, for example, to high demands imposed by the circuit design, such as in a switchmode power supply), necessitating "re-capping" (i.e. replacing many capacitors after disconnecting the power and waiting for lethal charge to dissipate).

日本語の意味
