T491D686M025AT Overview
Capacitor ripple current is set to 417mA.In a simple circuit consisting of a resistor and a perfect capacitor, equivalent series resistance (ESR) determines the amount of valuable energy lost. All circuits with a resistor and a capacitor have 700mOhm as their resistance.Currently, this capacitor is leakage current 0.017mA.Whenever AC is applied through a capacitor, the dissipation factor is 10 %.Insulating oil has a tan delta of 0.1 when it goes through an electric dielectric test to determine its quality.
