(3) Reliability

The malfunction rate of tantalum solid state electrolytic capacitors varies considerably depending on the conditions of

usage (ambient temperature, applied voltage, circuit resistance).

p

: Malfunction rate stemming from operation

b

: Basic malfunction rate

E

: Environmental factors

SR

: Series resistance

Q

: Level of malfunction rate

CV

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

capacitors column in MIL-HDBK-217.
