Electrical characterization
Electrical characteristics should meet values as given chapter
“Electrical data”.
-
The capacitance and the
dissipation factor should meet the
specification at 25 °C.
-
Capacitance must fulfil the
X7R characteristics within the
range of -55 to 125 °C.
-
Insulation resistance must
meet specification at 25 and 125
°C where defined.
-
MLCC must pass dielectric
strength test (2.5 times rated
voltage, 5 s, surge current < 50
mA).

Board flex
∆C/C within ±4.5%
∆C/C within ±7.5% for 25 V
D.F. < 25 · 10
-3
D.F. < 50 · 10
-3 for 25 V
I.R. > 1 · 10
5 MΩ or τ > 1000 s resp. 500 s for 25 V
(whichever is less)
Fix the capacitor on PCB and apply a
force until a deflection of 2 mm is
reached for 5 ±1 s, 1 mm jig radius, 90
mm supporting span, speed 1 mm/s. for
land pattern design and drawing of the
test setup please see appendix “Effects
of mechanical stress”.
