Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Virtually every type of electronic hardware incorporates capacitors, which are widely used for functions such as bypassing, coupling, filtering, and tunneling electronic circuits. However, to be ...

Kemet has introduced what it calls the industry’s first COTS grade polymer electrolytic capacitor with a 1,000-hour life test option. The new option, also known as the "Biased Humidity Test," provides ...

The tool covers all the company's high-voltage capacitors (>150 V DC) with screw, snap-in and solder pin connections. TDK released the fully-revised version 4.0 of their Online AlCap Useful Life ...

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 ...

Workbench contributor and engineer Duke Evans writes that he has repaired many a circuit board trace with bare wire. In his years of circuit board repairs, Duke has also noted that some older ...

Ever wonder what’s inside an electrolytic capacitor? Many of us don’t, having had at least a partial glimpse inside after failure of the cap due to old age or crossed polarity. The rest of us will ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
