Description
This specification defines the qualification program forminiature aluminum electrolytic capacitors with leads. Thequalification program is defined in table 1. Specification sheetscan be added, as required, to define specific products or to coverunique/specific requirements.
Preconditioning
Before starting the qualification program, all capacitors shallbe preconditioned by the application of the rated voltage from adirect voltage source having a low internal resistance, such as aregulated power supply. The voltage shall be applied to thecapacitor through a resistor. The resistor shall approximately be100 ohms for rated voltages up to and including 100 V, and 1000ohms for rated voltages above 100 V.
The voltage shall be maintained for 1 hour. Afterpreconditioning, the capacitors shall be discharged through a resistor of approximately 1 ohm per applied volt.
The capacitors shall be allowed to stabilize for a period of 12hours to 48 hours, without any applied voltage, prior to beginningqualification test program.
