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 ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Aluminum electrolytic capacitor technology underpins critical energy storage systems with aluminium foils serving as the anode material. Recent innovations focus on optimising the microstructure of ...

Note: For a PDF version of this article, click here. Aluminum electrolytic capacitors remain a popular choice in power supplies due to their low cost. However, they have limited life and are sensitive ...

TDK’s B41699 and B41799 series of aluminum electrolytic capacitors offer high capacitance and high ripple current in a ...

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 ...

Accurate modeling of power electronic converters, i.e., obtaining control to output transfer function, must include series resistance of capacitors and inductors. A simple method allows measurement of ...
