Formula for calculating malfunction rate λp = λb × (πE × πSR × πQ × πCV) λp : Malfunction rate stemming from operation λb : Basic malfunction rate πE : Environmental factors πSR : Series resistance πQ : Level of malfunction rate πCV : Capacitance For details on how to calculate the malfunction rate stemming from operation, see the tantalum solid state electrolytic capacitors column in MIL-HDBK-217.
