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).
