(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)

capacitors column in MIL-HDBK-217.

Note: Solder the chip at 300°C or less. If it is soldered using
a temperature higher than 300°C, open function built-in may operate.
(7) Maximum power dissipation
Warming of the capacitor due to ripple voltage balances with warming caused by Joule heating and by radiated heat.
Maximum allowable warming of the capacitor is to 5°C above ambient temperature. When warming exceeds 5°C, it can
damage the dielectric and cause a short circuit.

Power dissipation (P) = I $ R
Ripple current
P : As shown in table at right
R : Equivalent series resistance
Notes:
1. Please be aware that when case size is changed, maximum allowable power dissipation is reduced.
2. Maximum power dissipation varies depending on the package. Be sure to use a case which will keep warming within
the limits shown in the table below.

(11) Ultrasonic cleaning
Carry out cleaning under the mildest conditions possible. The internal element of a tantalum capacitor are larger than
those of a transistor or diode, so it is not as resistant to ultrasonic waves.

Tantalum capacitors
1) Do not allow solvent to come to a boil (kinetic energy increases).
2
$ Ultrasonic output
0.5W / cm or less
$ Use a solvent with a high boiling point.
$ Lower solvent temperature.
2) Ultrasonic cleaning frequency
28 kHz or less
3) Keep cleaning time as short as possible.
4) Move item being cleaned.
Standing waves caused by the ultrasonic waves can cause stress to build up in part of the item being cleaned.

Kinetic energy = 2 x π x frequency x
2 x ultrasonic output
