== Fundamentals == The principal properties of a capacitor are capacitance, working voltage, [[equivalent series resistance]] (ESR), [[equivalent series inductance]] (ESL), and working temperature Compared with electrolytic capacitors usually used for power supply filtering at [[utility frequency|power frequency]], a photoflash capacitor is designed to have lower ESR, ESL, and capacitance [[manufacturing tolerance]], but does not need as high a working temperature.
