Engineers need to fit components into small power supplies. These capacitors help make electronics smaller while keeping ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

New graphene material from Monash enables supercapacitors with battery-level energy and lightning-fast charging.

In a breakthrough for next-generation technologies, scientists have learned how to precisely control the behavior of tiny ...

Abstract: Resonant switched-capacitor circuits are attractive for power integration, but encounter limited voltage regulation range and efficiency. This article proposes a family of quasi-parallel ...

A new thermogalvanic device uses nanoparticles to control ion flow, allowing it to convert waste heat to electricity and store the energy without external batteries.

In August of 1859, astronomers noticed an unusually large number of dark spots on the sun’s surface. One of those observers ...

TDK Corporation introduces the B3270xP, a series of ultra-small, metallized polypropylene (MKP) film capacitors tailored for ...

In this video, we build a buck-boost converter using the powerful and affordable XL6019 chip, paired with a handmade bifilar common-mode choke. The video showcases a custom-designed buck-boost ...

Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at ...

Quantum computing, an approach to deriving information that leverages quantum mechanical effects, relies on qubits, quantum ...
