(4) Reliability
The malfunction rate of tantalum solid state electrolytic capacitors varies considerably depending on the conditions of
usage (ambient temperature, applied voltage, circuit resistance).
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.
