T491B475K025AT Overview
In this case, 238mA is the ripple current of the capacitor.Equivalent series resistance (ESR), also known as internal resistance, is a value representing the loss of useful energy in a simple electronic circuit consisting of a resistor and an ideal (perfect) capacitor, and its resistance is 1.5Ohm.This capacitor leaks current at 1.2μA.Dissipation factor is the amount of power lost by a capacitor when AC is applied through it, and this capacitor has dissipation factor 6 %.The tan delta of the insulating oil is 0.06 based on its electrical dielectric test.
