Electronically-variable capacitors, whether used for T&M or in an end circuit, usually have a maximum capacitance of a few hundred picofarads, and a limited adjustment range. This Design Idea ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Single-cell EC capacitors can reach 50,000 + farads. Daniel O'Brien, North American Capacitor Corp., Greencastle, Ind. All capacitors consist of two metallic electrode plates separated by an ...

Emerging applications like 5G communications and evolving automotive requirements such as for advanced driver-assistance systems (ADAS), autonomous driving, and on-board chargers for electric vehicles ...

Switched-mode power supplies (SMPS) and low dropout (LDO) regulators are found in electronic systems. Critical SMPS requirements include a stable output voltage with load current, good temperature ...
