Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Figure 1: How capacitance is calculated ...

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) ...

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 ...

A capacitor rarely fails loudly. It fails quietly, and that’s what makes it dangerous. I remember debugging a compact PLC power board used in a packaging line. The system worked perfectly on the bench ...

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, ...

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 ...

Ever wonder what goes on inside of an electrolytic capacitor? Nick Visic from AiSHi Capacitors shows how these popular capacitors work in this tear-down video from DesignCon. The screw terminal ...

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 ...

Bypass capacitors are frequently needed in electronics development. Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass ...

Custom Electronics, Inc. (CEI) designs and supplies various high-voltage, high-temperature mica capacitors and subcomponents. Since 1964, CEI has successfully designed and manufactured the ...

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 ...
