(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 p = b x (E x SR x Q x CV) p b E SR Q CV : Malfunction rate stemming from operation : Basic malfunction rate : Environmental factors : Series resistance : Level of malfunction rate : Capacitance

(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 5C above ambient temperature. When warming exceeds 5C, it can damage the dielectric and cause a short circuit. Power dissipation (P) = I2 ! 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.

Inrush current
Beware of inrush current. Inrush currents are inversely proportional to ESR. Large inrush currents can cause component failure.

(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. Example : water Propagation speed Solvent density

Tantalum capacitors
Precautions 1) Do not allow solvent to come to a boil (kinetic energy increases). ! Ultrasonic output 0.5W / cm2 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. Reference
Kinetic energy = 2 x x frequency x 2 x ultrasonic output propagation speed x solvent density
