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 ...

Bypass capacitors are found in every working piece of electronic equipment. Most engineers know that systems, circuits, and individual chips need to be bypassed. The methods for choosing bypass ...

Capacitors may seem simple enough, but specifying them has grown more complex in recent years. The reason why comes down to freedom of choice. The universe of capacitors for embedded systems ...

As you will probably already know if you are engaged in electronics design at some level, a capacitor is a passive device ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
