Fixed inductors, also known as inductors, coils, or reactors, are electrical components designed to create magnetic fields and to store electromagnetic energy. Commonly used in a variety of applications, they are found in instruments, amplifiers, receivers, radios, and variable speed drives. The 0925R-394K fixed inductor is one of the most common and widely used types of these components.This particular fixed inductor is incredibly small, measuring only 3.94 mm in diameter and height, and having a rated inductance of 5.5+/-20%. It is designed to handle a maximum direct current (DC) of 300 mA, with a rated DC resistance of 16 milliohms and a saturation current of 1050 mA. What’s more, the component features an inductance tolerance of -+0.2%, and an environmental temperature range of -40°C to +105°C.Due to its small size, the 0925R-394K fixed inductor is extremely useful in a number of applications, particularly where space is at a premium. For instance, it is often used in amplifiers, receivers, radios, and variable speed drives, as well as in computer motherboards, LED lamps, and other small electronic components. Additionally, it is ideal for signal filtering and noise suppression in portable devices such as cell phones, tablet computers, and portable music players.The 0925R-394K fixed inductor has a wide range of working principles which make it an ideal component for a variety of purposes. Most notably, it works by storing energy in a magnetic field, which is created when a current flows through the inductor. This is achieved by passing a current through the inductor, thus inducing a magnetic field which causes a flux to be created. This flux in turn causes a counter-electromotive force, or back emf, which opposes the change in current, thus clamps the current to a certain value.In addition, the 0925R-394K fixed inductor is also able to act as a choker or blocking diode to change the frequency of electric signals. It does this by providing a path for current which is out of phase with the frequency of the signals, thus resulting in a decrease in frequency. As a result, the component is used in a range of both AC and DC applications, from signal filtering and noise suppression to voltage stabilizing.Overall, the 0925R-394K fixed inductor is an incredibly useful and versatile electrical component and is used in a number of different applications. Due to its size, it can be used in devices where space is at a premium, while its working principles make it well-suited for various AC and DC applications. Whether it’s used for amplifiers, receivers, radios, variably speed drives, LED lamps, signal filtering or noise suppression, this small yet powerful component is an essential addition to many circuits.
