EPCOS has optimized its discharge resistor modules based on hybrid ceramics to simplify mounting of discharge resistors on PFC capacitors and enhance reliability. The new module is no longer supplied ...

[Editor's Note: This tech bite was originally posted on the Fairchild Semiconductor website. Richard Chung, the applications manager at Fairchild, would like to bring these tech briefs from his team ...

Electronic enthusiasts may be interested in a new versatile RLC-Box created by electronics hobbyist Roger Leifert based in Aachen, Germany. With 3 rotary-switches you can select from 8 decades of ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start. Overheating is a primary cause ...

If you build electronic circuits on a regular basis the chances are you will have used capacitors many times. They are a standard component along with the resistor whose values are lifted off the ...

Figure 1: The four fundamental two-terminal circuit elements: resistor, capacitor, inductor and memristor. The rich hysteretic i–v characteristics detected in many thin-film, two-terminal devices can ...
