Capacitors are small components with a big job—storing and releasing energy in electronic circuits. This video explains how ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

Capacitors are tiny components that store and release electrical energy in a split second. This video explains how they work, ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

New capacitors covering the 5-µF to 60-µF range have been added to the EPCOS line of 4-pin link circuit capacitors operating on voltages from 250 Vdc (180 Vac) to 850 Vdc (350 Vac). The capacitors are ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

Q. What is the minimum ampacity and minimum size conductor required for a circuit that connects a capacitor to the terminals of a 25 hp, 460VAC, 3-phase, air conditioner induction motor? The rated ...

One of the last remaining unshrinkable obstacles blocking the progress of fully integrated, wearable technology is the clunky component that absorbs and disburses stray electricity and converts ...

Illinois Capacitor’s new all-weather “MPX/MPXB” Series metalized polypropylene capacitors suppress conducted electromagnetic/radio frequency interference (EMI/RFI) before it can be transmitted via ...
