1. Preconditioning, class 2 only:
150 +0/-10 °C /1 hour, then keep for
24 ±1 hour at room temp
2. Initial measure:
Spec: refer initial spec C, D, IR
3. Endurance test:
Temperature: X7R: 125 °C
Specified stress voltage applied for 1,000 hours:
Applied 2.0 x Ur for general product.
Applied 1.5 x Ur for high cap. product.
4. Recovery time: 24 ±2 hours
5. Final measure: C, D, IR
P.S. If the capacitance value is less than the minimum
value permitted, then after the other measurements
have been made the capacitor shall be precondition
according to “IEC 60384 4.1” and then the
requirement shall be met.
