Effects of ESL on the performance of capacitors

source: Capacitor Faks blog Capacitors are widely used in electronic circuits for storing and managing energy. Typical applications include filtering, decoupling, energy storage, and tuning. Some applications such as decoupling demand low impedance, high ripple current capability, and excellent surge performance. Inductance is one of the key parameters to consider when selecting a capacitor for […]

Lamborghini moved away from standard batteries and focused on supercapacitors at their Terzo Millennio concept

source: CNET news Lamborghini teased a concept last week for MIT’s EmTech conference. Now it’s here, and it’s crazier than the teaser let on. The Lamborghini Terzo Millennio concept is the result of collaboration between Lamborghini and MIT Massachusetts Institute of Technology, wherein the two parties are digging into materials research and other automotive-related areas. […]

Applications of Exciter Discharge Resistors

source: AZO Materials news An exciter in a synchronous generator is used to deliver the DC supply to the electromagnetic field winding which is mounted on the generator’s rotor. An appropriate means to discharge the stored energy in the field coil should be available in order to prevent damage that is being sustained to excitation […]

When benign is better: fail safe capacitor technology

Source: Capacitor Faks blog The performance of a capacitor greatly depends on the environment in which it is used. Exposing a standard capacitor to extreme conditions can cause it to fail, overheat, or even burn. For semi-critical and critical applications, it is necessary to use high reliability components. Fail safe capacitors are designed to withstand […]

Leakage current characteristics of capacitors

source: Capacitor Faks blog Capacitors, just like other electronic components, are constructed with imperfect materials. The imperfections and defects in these materials have significant effects on the electrical performance of capacitors.  Some of the parameters determined by these defects and imperfections include impedance, dissipation factor, inductive reactance, equivalent series resistance, and leakage current. When designing […]
