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 to initial spec C, D, IR
3. Endurance test:
Temperature: X5R: 85 °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*.
Applied 1.0 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 preconditioned
according to “IEC 60384 4.1” and then the requirements
shall be met.
