The capacitance of certain capacitors depends not only on the chosen dielectric material, geometry and temperature, but also on the DC and AC bias applied to the part. Some ceramic capacitors with high volumetric density today exhibit a strong dependence on the DC and AC bias. To achieve high...

When DC-rated capacitors are to be used in AC or ripple current circuits, be sure to maintain the Vp-p value of the applied voltage or the Vo-p which contains DC bias within the rated voltage range. When the voltage is started to apply to the circuit or it is stopped applying, the ...

陶瓷电容器被广泛运用于PI旁路和SI高速通道的直流阻断。然而,随着电容器尺寸的不断缩小,陶瓷电容器因外加直流和交流激励而产生的电容损失和损耗变化变得越来越明显,我们需要多维数据来捕捉这些影响。本讲座将介绍测量设置和python自动化,它可以自动扫描多个参数,并允许我...
For a start, capacitance can be affected by the operating temperature, applied DC bias, and time after last heat. The time after last heat, for instance, can cause a shift in capacitance, which leads to capacitor aging (Figure 2). EIA CodePME (Precious Metal Electrodes) BME (Base Metal ...
