(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 : Malfunction rate stemming from operation

λb : Basic malfunction rate

For details on how to calculate the malfunction rate stemming from operation, see the tantalum solid state electrolytic

capacitors column in MIL-HDBK-217.
