RF Transformers are two, or more, port passive devices with a wide range of uses for many RF applications. One of the most common uses of an RF transformer is the Balun, which provides efficient coupling between unbalanced transmission circuits and balanced circuits. Other common uses are for impedance matching between circuits of different impedances. Other applications include DC isolation, injecting DC current, or enhancing the common mode rejection of a circuit. (more…)

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…)

by Rudy Ramos, Technical Content Marketing at Mouser Electronics. Jul 31, 2018. Capacitors can provide vital ride-through (or hold-up) energy or mitigate ripple and noise in power-conversion circuits. Choosing the right type can profoundly affect a system’s overall size, cost, and performance. (more…)
