Why low ESR matters in capacitor design
Source: Capacitor Faks blog, EPCI
by Anthony Kenny (Capacitor Faks) and Tomas Zednicek (EPCI). A practical capacitor is a non-ideal component. Its circuit model contains series inductance (ESL) and series resistance (ESR). Although equivalent series resistance is often shown in circuit models as a constant value, it varies depending on operating conditions. ESR is resistance from a combination of energy loss mechanisms under specific operating conditions. (more…)
