(6) 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) = 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. Allowable power dissipation (W) and maximum temperature rising

(10) Ultrasonic cleaning Carry out cleaning under as mild conditions as possible. The internal element of a tantalum capacitor are larger than those of a transistor or diode, so it is not as resistant as ultrasonic waves. Example : water Propagation speed Solvent density
Frequency and wavelength
Frequency Wavelength 20kHz 7.5cm 28kHz 5.3cm 50kHz 3.0cm

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
Kin etic energy = 2 x x frequency x 2 x Ultrasonic output propagation x speed x solvent density
