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.
The capacitors shall be subjected to IEC 60068-2-21, Test Uc, as applicable. Method A, severity 2 (two successive rotations of 180°) shall be used. This test shall not apply is in the detail specification the terminations are described as rigid and to components with unidirectional terminations designed for printed wiring applications.
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.
This document shows how the ESR of a capacitor is measured from 10 Hz to 1 MHz using the Bode 100 vector network analyzer. The datasheet of the capacitor does provide the following information about the ESR of the capacitor: At 120 Hz and 20 °C the tan respectively the Dissipation Factor DF is specified with a maximum value of 20% (= worst case).
The capacitance at 10 Hz equals 993 μF. At approx. 90 kHz the capacitor shows a series-resonance due to the internal inductance. The exact series-resistance value can easily be measured by activating a cursor. To compare the measured ESR with the value from the datasheet the cursor is set to a frequency of 120 Hz.
In the 100 kΩ setting, the parasitic cap at the inverting pin can make the circuit unstable. To overcome this problem a 5 pF capacitor is added in parallel with RF = 100 kΩ. It must be noted that one time calibrations are done at all four frequencies of operation.
