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 ...

Variable capacitors are electronic components that allow for the adjustment of capacitance within a circuit. They are designed to store and release electrical energy, with the unique feature of being ...

(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the ...

Amateur Radio as a hobby has a long history of encouraging experimentation using whatever one might have on hand. When [Tom Essenpreis] wanted to use his 14 MHz antenna outside of its designed ...

Description: The NCD2100 is an EEPROM based digitally programmable variable capacitor that provides capacitive offset trimming for capacitance sensitive circuits. Programming the non-volatile EEPROM ...
