Capacitor performance across temperature, voltage, frequency, and time should be considered, but this data is not always prevalent on a datasheet. Capacitor specifications of capacitance, DC leakage current (DCL), equivalent series resistance (ESR), size, etc. are typically room temperature measurements under a very specific test condition
Dissipation Factor (DF), Quality Factor (Q), and Equivalent Series Resistance (ESR) are important parameters of high performance capacitors. Their role in low-impedance or high-current circuits such as power supplies, high-current amplifiers, and filters, is especially significant.
