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 ...

Instructable user [EngineeringShock] got sick of buying batteries for his devices all the time and has instead opted to build himself a super capacitor bank that can be used to power common household ...

Tantalum surface-mount capacitors have gained widespread favor for bulk decoupling use in both conventional and switch-mode power supplies (SMPSs) since their introduction more than 20 years ago.

Find a downloadable version of this story in pdf format at the end of the story. In any industry, there are applications whose failure could mean lost revenue and increased annoyance. In very few ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...

Philips’ researchers have micromachined electrically variable RF capacitors. The devices, which are the microscopic equivalent of air-spaced variable and switchable capacitors, can be integrated into ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

The inverters and charging systems in hybrid or fully electric vehicles provide a topical example of a high-voltage application that faces extreme space constraints. When multilayer ceramic capacitors ...
