Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

The Type PFCH capacitor series from Cornell Dubilier Electronics, intended for the ac output of large inverter systems, filter undesirable harmonics before power is delivered to the grid or load. The ...

Ah, the age old tradition of Dumpster diving! Sometimes we happen to spot something that’s not quite trash, but not quite perfect, either. And when [dzseki], an EEVblog.com forum user, spotted some ...

Although SPICE can be a powerful tool, there are pitfalls in relying solely on simulation. To avoid unpleasant surprises, it's imperative that a SPICE simulation be anchored to a detailed ...

In the past five to ten years, there has been a big shakeout in the capacitor industry with at least 15 major manufacturers ceasing production for various reasons. Product lines have also been ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...
