The history of capacitors starts in the pioneering days of electricity. I liken it to the pioneering days of aviation when you made your own planes out of wood and canvas and struggled to leap into ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

The subject of capacitors seems quite attractive from the standpoint of having low values of equivalent series resistance (low ESR) but there might be an issue which we see when we extract a small ...

Regular readers of Hackaday are intimately knowledgeable about old electronics, and whether it’s about that old oscilloscope sitting in the pile of other oscilloscopes, or the very rare vintage ...

There is a general trend of making electronics smaller and with more functionality. This translates into: “Cram it in there,” so naturally designers look to find smaller and smaller parts. What was on ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

There was a recent news item regarding a teenager's project to use a super capacitor as a quick-charging energy storage device. The primary claim is that this could be used to fully charge a phone in ...

Out of all of the fundamental passive electronic components, capacitors are arguably the most abundantly used. In fact, it is hard to find a circuit board that does not have a capacitor on it and a ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...

Combining the unique strengths of lithium batteries with crazy-fast charging, carbon ultra-capacitors could save a ton of weight and add significant range and power to electric vehicles, according to ...
