Surface-Mount Ceramic Multilayer Capacitors
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. Damp heat test:
500 ± 12 hours at 40 ± 2 °C;
90 to 95% R.H. 1.0 Ur applied
4. Recovery:
Class 1: 6 to 24 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 requirement shall be met.
No visual damage after recovery
<General purpose series>
∆C/C
Class 1:
NP0: within ± 2% or 1 pF
whichever is greater
D.F.
Class 1:
NP0: ≤ 2 x specified value
Rins
Class 1:
NP0: ≥ 2,500 MΩ or Rins x Cr ≥ 25s
whichever is less
