T491C157K004AT Overview

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 1.2Ohm in this case.The leakage current of this capacitor is 0.006mA. A capacitor's dissipation factor determines how much power is lost when AC is applied through it, and its dissipation factor is 8 %.The Tan Delta test of insulating oil determines its quality by measuring its electrical dielectric properties.
