Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

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.

The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...

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 ...

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, ...

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 ...

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.

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 ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

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 ...
