Product specification 18
Surface-Mount Ceramic Multilayer Capacitors General Purpose & High Cap. X7R 6.3 V to 50 V 20
TEST
Damp Heat
with Ur Load
TEST METHOD
IEC 60384- 4.13
21/22
PROCEDURE
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 2: 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 requirement shall be met.
REQUIREMENTS
No visual damage after recovery
