T491D685K035AT Overview
The capacitor's ripple current is set to 136mA.Known as internal resistance, equivalent series resistance (ESR) is the loss of energy in an electronic circuit containing a resistor and an ideal (perfect) capacitor, whose resistance is 1.3Ohm in this case.There is a leakage current of 6μA in this capacitor.A capacitor's dissipation factor is the power lost when AC is applied to the capacitor, which is 6 %.The Tan Delta test of insulating oil determines its quality by measuring its electrical dielectric properties.
