DINFENG CAPACITOR---What is the tangent of loss angle or dissipation factor?

Update Time:2018/6/13

If we give a voltage to a capacitor, current will not only charge the capacitor, but also leakage (capacitor leakage current). And the leakage current is burned into heat energy wasting in wires, so we express the leakage current as the current on resistance.

Tangent of loss angle is the ratio of leakage current to all current (tips: In the theory, capacitor is not waste electricity power).
