平均故障間隔時間（MTBF）
由於工作溫度是確定整體模組可靠性的最重要因素之一，重要的是用戶的系統設計可以有效地將熱從基板傳遞到系統環境。由於溫度和故障率是指數關係，基板溫度只降低10℃，就可致MTBF的明顯增加。由於專利的零電壓/零電流開關拓撲結構，相比那些更傳統的拓撲結構，Vicor轉換器效率更高。高效率意味著更小的尺寸和更低的溫度升高。為了最大限度地減少熱阻抗，所有主要功率耗散組件都直接安裝在基板上。
下面代表的是根據MIL-HDBK-217F計算的MTBF值。如果你需要有關特定型號的資訊，請根據型號、預期基板溫度和工作環境與Vicor聯繫，以獲得需要的報告。

環境認證
附加环境测试可以根据具体客户的要求完成。完全封裝的Vicor Maxi、Mini、Micro和MI系列模組採用專有的旋轉填充工藝，保證完整、無空隙的封裝，使之適合於惡劣環境。除了提供機械強度，密封還是導熱的，以消除熱點並有助於熱量傳遞到基板上。模組可在溫度低至-55℃工作並在-65℃貯存。
為了驗證Vicor的H及M級Maxi、Mini和Micro以及MI系列模組惡劣環境的適用性，這些產品都經過MIL-STD-810, 和MIL-STD-202的環境測試。下面列出的這些測試是在獨立實驗室進行的。附加環境測試可以根據具體客戶的要求完成。
