On big aluminum capacitors, the values are usually written out in cleartext. For example, if it says 2200 µF 16V, that’s the capacitance value and the voltage rating. But often on smaller capacitors, you instead have cryptic numbers. Like 102, 223, or 474. In these cases, the first...
Let's take a closer look at capacitors and how they work!Photo: A typical capacitor used in electronic circuits. This one is called an electrolytic capacitor and it's rated as 4.7 μF (4.7 microfarads), with a working voltage of 350 volts (350 V)....
Oscillating Circuits The oscillator circuit components at work. Energy needs to move back and forth from one form to another for an oscillator to work. You can make a very simple oscillator by connecting a capacitor and an inductor together. If you've read How Capacitors Work and How Induc...

Bootstrap Capacitors in a Switching Regulator Bootstrap capacitors are used in synchronous or asynchronous switching regulators to aid switching action in aMOSFET. Most often, they are used in synchronous switching regulators. The placement of the bootstrap capacitor in these circuits is such that it...
As a functional circuit, IC can be directly applied on PCB, improving compact features and reliability of the PCB. Then, PCB with IC is used in many high-tech industry, such as smart automotive, IoT, smart medtech, telecom and artificial intelligence. ...
capacitors, specifically Class Y safety capacitors. Also known as Y-type safety capacitors, these capacitors play a dual role of determining leakage current and suppressing radiated emissions. The EMI suppression function of these capacitors is quite simple, and will show you how it works in this ...
Capacitors consist of two conducting surfaces separated by an insulator; a wire lead is connected to each surface. What is Capacitor and How Capacitors Work Capacitor Symbol and Unit There are two capacitor symbols generally used inelectronics. One symbol is for polarized capacitors, and the other...
Capacitors, in electrical circuits, work by storing electric charge between their plates, and over time the capacitor starts to lose its efficiency, and it can be caused by multiple reasons. These include overheating, fluctuations in voltage and current values, and other similar reasons. ...
