Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, ...

Some 99 percent of the “design” problems associated with linear and switching regulators can be traced directly to the improper use of capacitors: wrong type, wrong value, or incorrect physical ...

Over the last 40 years, a series of misconceptions regarding mica capacitor applications has led novice users to consistently over-derate wound or rolled mica/epoxy dielectric capacitors. The mined ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

Tantalum capacitors offer designers of densely packed, high-performance electronic circuits a reliable high-capacitance solution with stable performance. A historical favorite among design engineers, ...

Capacitors. These seemingly simple devices are an integral part of virtually every electronic design. It’s been noted that capacitors account for more items in most circuit bills-of-material (BOMs) ...

One common trend in switch-mode power supplies, microprocessors and digital circuit applications is the reduction of noise while operating at higher frequencies. In order to make these possible ...

Few passive components exist in the sheer variety of forms that the capacitor has taken. Simple in principle, the design of the capacitor involves a number of tradeoffs that make it impossible to ...

When a crew employed by a local electric utility set out to conduct a DC hi-pot test on a new circuit breaker, the task seemed like nothing more than a routine call. Unfortunately, the events that ...

TOKYO — Toshiba Corp. has developed a one-transistor, no-capacitor cell structure that it claims solves the difficulties encountered in producing DRAMs in sub-0.1-micron process technology. The ...
