T491B475M025AT Overview
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.The dissipation factor of a capacitor is the amount of power lost when current is applied through it, and the dissipation factor of this capacitor is 6 %.The Tan Delta is a dielectric test on the insulating oil to determine its quality, and it is 0.06.
