The tube with the aluminum foil is a capacitor and the tube with the wrapped wire is an inductor. Together (with a diode and an earpiece) these make a crystal radio.

In DC voltage applications, the RC snubber network is typically wired across the relay contacts, whereas in standard AC ...

Capacitors fail. It’s what they do. Aluminum electrolytics caused my monitor power supply to fail.A failed capacitor took down Paul Rako’s air conditioner.This is a story of how two burned capacitors ...

Four diodes and one capacitor. It doesn't get simpler than that - but it can get more complicated. Newer and smaller AC to DC converters often use other methods to produce a DC current.

If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used t… ...

Silanna Semiconductor announced the release of the SL2002, the second breakthrough product in its FirePower family of laser ...

8-Channel ReDriver with Internal Coupling Capacitors from Diodes Incorporated Enhances Signal Quality in High-Speed UPI 2.0 and PCIe 4.0 Interfaces July 27, 2021 10:14 AM Eastern Daylight Time ...

It’s a voltage follower, but not exactly wired as one since the output is fed back to the diode. It keeps the voltage across the diode close to 0 (or voltage change if a capacitor is used). So ...

Asymmetric Output Into Capacitor Load Turns Capacitor Into Ideal Diode April 10, 2013 This comparator circuit detects the presence of a small ac signal on a 2.5-V dc reference, creating a 5-V ...
