The amount of energy that is stored, measured in farads.
Dissipation Factor (DF):
The percentage of energy wasted as heat in capacitor.
Equivalent Serious Resistance (ESR):
Another measure of energy dissipated as heat in a capacitor and is directly proportional to DF.
The measure of the opposition that a circuit presents to a current when a voltage is applied.
The DC resistance of the capacitor and is related to the leakage current, measured in Ohms.
Dielectric Withstanding Voltage (Dielectric Strength):
The maximum voltage a capacitor can sustain, above its standard operating voltage, with no damage. Devices are generally raised to this voltage for 5 minutes and devices are examined with high power microscopy for damage, such as cracks.
The changes in parametric performance at different temperatures, and the ability of the device to stay within parametric specific range at maximum and minimum operating temperatures.
Quality factor (Q):
A calculated measurement and is fundamental losses of energy in a resonant system.
