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 ...

The NCD2100 electronic programmable capacitance IC has a capacitance range of 6.6 to 37.55 pF in small 63-fF steps for shunt configuration. The digitally controlled capacitance trimming setting is ...

The Range comprises five types of operation in high voltage r.f. circuits. All are tunable over an approximately linear capacitance range. High vacuum variable capacitors offer outstanding advantages ...

While working on electronics projects, it’s often necessary to test out different capacitance or resistance values as things are moving along. Depending on what you are testing, this can be a tedious ...

How do you implement a variable capacitor these days? Mechanical caps are out. That leaves varactors, which work fine but require higher voltages that often are not available, and their response is ...

Since we’re now halfway through the series, it’s probably a good time to look at the nameplate parameter for capacitors – the capacitance itself. In most capacitor applications, such as bypass and ...

This file type includes high resolution graphics and schematics. Cavendish Kinetics now offers a tunable RF micro-electromechanical systems (MEMS) capacitor that lets smart-phone antennas cover a ...
