电气性能

Electrical Properties

电气性能最稳定，几乎不随温度、电压和时间的变化而变化。

The electrical properties is  the most stable one and has little change with temperature, voltage and time.

具有较高的介电常数，容量可做到比I类电容器高，具有稳定的温度特性。

X7R material has high dielectric constant, and its capacitance is higher than class I. These capacitors are classified as having a semi-stable T.C..

温度特性介于X7R和Y5V之间，容量稳定性相对较差，对温度、电压等条件较敏感。

Temperature characteristic is between that of X7R and Y5V. The capacitance is unstable and sensible to temperature and voltage.

介电常数最大，但温度特性较差，对温度、电压等条件较敏感。

Y5V material has highest dielectric constant. Its capacitance and dissipation is sensible to temperature and voltage.
