The test conditions shall be defined in the detail specification. For all capacitors except those of item b) and c) below: IEC 60068-2-20, Test Tb, method 1 (solder bath). IEC 60068-2-20, Test Tb, method 2 (soldering iron). For surface mount capacitors, IEC 60068-2-58, reflow or solder bath method.
Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.
For a.c. rated capacitors the test voltage shall be d.c. capacitors the test voltage shall be UR. or the value required to limit the charge current to 1 A (or to the higher current value given in the detail specification) whichever resistance value is the greater.
At these parameters of the model the acceleration factors are large, and a 96-hour testing of capacitors at 2 times rated voltage (VR) and 125 °C during voltage conditioning (a typical screening procedure) would be equivalent to testing at operating conditions (assumed 50 °C and 0.5 VR) to more than a thousand years of operation (see Figure 1).
d.c. capacitors the test voltage shall be UR. or the value required to limit the charge current to 1 A (or to the higher current value given in the detail specification) whichever resistance value is the greater. such a value that the maximum rate of change of voltage (dU/dt) shall be approximately 100 V/Ps.
The capacitors shall be subjected to IEC 60068-2-1:2007, Test Ab. The capacitors shall be stored at -40°C for either a period of 4 hr after thermal stability has been reached, or for 16 hr, whichever is the shorter period.

Ceramic Capacitor FAQ and Application Guide
Q or quality factor represents the efficiency of a capacitor. It is the ratio of energy stored in a capacitor to the energy dissipated as thermal losses due to the equivalent series resistance (ESR) and I2R losses. Higher ESR can cause excessive heating in the capacitor at higher frequencies beyond its max allowable power dissipation. Since Q is inversely proportional to ESR, lower …
