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

Inrush current can be limited by means of a protective resistor.

(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.
