Description

This specification defines the qualification program for miniature aluminum electrolytic capacitors with leads. The qualification program is defined in table 1. Specification sheets can be added, as required, to define specific products or to cover unique/specific requirements.

Preconditioning

Before starting the qualification program, all capacitors shall be preconditioned by the application of the rated voltage from a direct voltage source having a low internal resistance, such as a regulated power supply. The voltage shall be applied to the capacitor through a resistor. The resistor shall approximately be 100 ohms for rated voltages up to and including 100 V, and 1000 ohms for rated voltages above 100 V.

The voltage shall be maintained for 1 hour. After preconditioning, 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 12 hours to 48 hours, without any applied voltage, prior to beginning qualification test program.
