具有低等效串联电阻（ESR）的铝电解电容器是高电容元件，通常用于平滑芯片的电源供应。整个2002年，它们一直在某些台式电脑上破裂并出现故障。到目前为止，唯一承认存在问题的主板生产商是台北阿比特电脑公司（ABIT Computer Corp.），唯一承认受到影响的大型个人电脑生产商是IBM公司（IBM Corp.）。但问题可能更为普遍。现在很清楚，电解液故障是造成电容器爆裂的罪魁祸首。显然，一位科学家从他在日本的雇主那里偷走了一种电解质的配方，并开始在一家台湾电解质制造商的中国分公司自己使用。然后，他或他的同事将配方卖给了台湾的一家电解液制造商，该制造商开始为台湾和其他电容器公司生产配方。不幸的是，出售的配方并不完整。
Aluminum electrolytic capacitors with a low equivalent series resistance (ESR) are high-capacitance components that generally serve to smooth out the power supply to chips. Throughout 2002, they have been breaking open and failing in certain desktop PCs. So far, the only motherboard maker to admit to the problem is ABIT Computer Corp. (Taipei), and the only major PC maker to acknowledge being affected is IBM Corp. But the problem is likely to be more widespread. It is clear now that a faulty electrolyte is to blame for the burst capacitors. Apparently, a scientist stole the formula for an electrolyte from his employer in Japan and began using it himself at the Chinese branch of a Taiwanese electrolyte manufacturer. He or his colleagues then sold the formula to an electrolyte maker in Taiwan, which began producing it for Taiwanese and possibly other capacitor firms. Unfortunately, the formula as sold was incomplete.
