There is most risk of vibration damage to capacitors in applications where high μF values are used where the parts are physically large, often with many paralleled. Examples would be in DC-link connections in inverters or motor controllers or output filters in high power AC-DC and DC-DC converters.
When the capacitor is mounted without any fixation on the PCB, or in case of high vibra-tion applications with common fixation on the PCB using special holders, potting or gluing, this will lead to additional vibration between the wire leads and the capacitor body as well as between the wire leads and the PCB.
